M Vim

Oh wow, trimming 'mvim' startup is one of those tiny joys that makes the whole day smoother. I usually start by profiling so I know what's actually slow: run mvim --startuptime ~/vim-startup.log and open that log. It quickly shows which scripts or plugins dominate time. Once I know the culprits, I move heavy things into autoload or optional plugin folders so they only load when needed.

Next, I use lazy-loading with a plugin manager like 'vim-plug' (Plug 'foo', { 'on': 'SomeCommand' } or 'for': ['python', 'javascript']). Put plugins you need immediately in 'start' and everything else in 'opt' or load by filetype. Also disable unnecessary providers (let g:loaded_python_provider = 0, let g:loaded_ruby_provider = 0) if you don't use them — that shave off seconds. Finally, keep UI tweaks minimal for GUI start: font fallback, complex statuslines and external helpers (like large LSPs) can wait until you open a project. After a few iterations of profile → defer → test, 'mvim' feels snappy and more pleasant to use.

Oh, this one used to confuse me too — Vim's mark system is a little quirky if you come from editors with numbered bookmarks. The short practical rule I use now: the m command only accepts letters. So m followed by a lowercase letter (ma, mb...) sets a local mark in the current file; uppercase letters (mA, mB...) set marks that can point to other files too.

Digits and the special single-character marks (like '.', '^', '"', '[', ']', '<', '>') are not something you can create with m. Those numeric marks ('0 through '9) and the special marks are managed by Vim itself — they record jumps, last change, insert position, visual selection bounds, etc. You can jump to them with ' or ` but you can't set them manually with m.

If you want to inspect what's set, :marks is your friend; :delmarks removes marks. I often keep a tiny cheat sheet pasted on my wall: use lowercase for local spots, uppercase for file-spanning marks, and let Vim manage the numbered/special ones — they’re there for navigation history and edits, not manual bookmarking.

Oh nice, this is easy to fix in Vim — that little 'm' for setting marks is super helpful, but sometimes you want to clear it out. In Vim, pressing m followed by a letter (like ma) sets a named mark in the current buffer, and those marks stay until you delete them or quit. If you want to see what marks you currently have, :marks is your best friend — it prints all the marks and where they point, including uppercase file marks and numbered marks. Jumping back to a mark is done with 'a or `a, but when you decide a mark has outlived its usefulness, you can delete it cleanly.

To remove marks, use :delmarks. It’s straightforward: :delmarks a removes mark 'a', and you can remove multiple at once by listing them like :delmarks abc. If you prefer ranges, :delmarks a-z clears all lowercase (buffer-local) marks, :delmarks A-Z clears uppercase (global file) marks, and :delmarks 0-9 clears the numbered marks. If you want to wipe everything in one go, either combine ranges (:delmarks a-z A-Z 0-9) or use the :delmarks! variant. The ! lets you delete marks across buffers (handy if you’ve been bouncing between files and want a fresh slate). Quick examples I use all the time: :marks to check, :delmarks a to drop a specific mark, and :delmarks a-z if I just want to clear all the little bookmarks in the current buffer.

If you like Vimscript tinkering, there's also :call setpos("'a", [0,0,0,0]) to stomp a mark by setting it to a null position — useful in scripts or mappings — but for casual interactive cleanup I stick with :delmarks because it’s explicit and readable. One tiny tip: uppercase marks (like 'A) are attached to filenames, so deleting them with :delmarks A-Z is useful when removing saved positions across files. And if you ever accidentally set a mark and jump to it, '' (two single quotes) gets you back to the previous location — lifesaver during frantic editing sessions.

Honestly, clearing marks is one of those small Vim rituals that makes sessions feel tidy again. I tend to run :delmarks a-z between big refactors to avoid weird jumps, or map a key if I need to reset often. Try the :marks command first so you don’t accidentally remove something you still need, and then use :delmarks with the specific letters or ranges. Happy editing — your buffer will thank you, and you’ll have fewer surprise hops when navigating!

Marking stuff in Vim feels like leaving tiny breadcrumb trails — and that little 'm' command is where the magic starts. I got tripped up by it a dozen times when I first tried to use marks the way I use bookmarks in browsers. Rookie mistakes with 'm' are usually about expectations: how marks behave, how to jump to them, and how easy it is to overwrite them without noticing. Once you get past the initial awkwardness, marks become one of those features you wonder how you lived without while hacking through a big file or bouncing between multiple source files.

The most common slip-ups I see (and made myself) are: confusing lowercase and uppercase marks, mixing up the single-quote and backtick jumps, accidentally overwriting marks, and assuming marks behave like registers. Lowercase letters (ma, mb, etc.) set named marks inside the current file; uppercase letters (mA, mB) are meant for marking positions across files. A lot of beginners type 'm a' with a space and wonder why nothing happens — the correct form is 'ma' with no space. Another classic: expecting 'ma' to move the cursor — it only sets the mark at the current cursor position. To go back, you use ''a or `a, and that difference matters: single-quote followed by a letter jumps to the start of the line of the mark, whereas backtick goes to the exact column. I would always reach for the single-quote when I really needed the column position and get irritated at myself for it. Also, marks are easy to overwrite — reusing 'a' will replace the previous 'a' mark silently — so I started the habit of choosing meaningful letters (like 's' for start-of-function) or using uppercase for file-wide anchors.

To make marks actually useful, I developed a couple of tiny habits that helped a lot. First, always check whether you want the line-level or exact-column return and use ' or ` accordingly. Second, reserve a few letters for persistent anchors (like 'F' for frequently visited file location); that reduces accidental overwrites. Third, if you find yourself jumping around a lot, learn the special marks: '' (back to last jump), '. (last change), and " (where you last left off) — these save so much time during refactors. I also recommend pairing marks with visual hints: plugins like vim-signature or simple annotations in code help you remember what a mark letter was intended for. And if you're ever unsure, :help marks is surprisingly clear and will save you from guessing.

Ultimately, marks turn Vim from a file editor into a navigation playground once you stop treating them like registers and start treating them like sticky notes you can jump to. Play around with ma/`a/'a for a day, and your workflow will feel snappier — just don’t go smashing letters randomly or you’ll have to rebuild your little breadcrumb map. If you want, try a tiny exercise: set three marks, jump around, edit, then use the special marks to return to last change and previous location — it’s oddly satisfying and a real productivity booster.

Totally doable — and honestly, if you care about startup speed and responsiveness, moving Lua into your editor config is one of the cleanest moves I’ve made.

I switched much of my setup to a Lua-first workflow (using Neovim) and noticed two big wins: faster plugin startup because plugin managers written in Lua can lazy-load better, and less overhead in your config because Lua is just faster than complex Vimscript. If you’re asking about "m vim" specifically (like MacVim or an ordinary Vim build called mvim), it comes down to how that binary was compiled. Vim can support Lua or LuaJIT if it was built with +lua or +luajit; Neovim, on the other hand, has first-class Lua from 0.5 onward and feels designed around it.

Practical tip: check vim --version for +lua or +luajit, or just try :lua print('hi') inside the editor. If you want the smoothest, fastest Lua experience, I recommend trying Neovim and using an init.lua plus a Lua plugin manager like packer.nvim or lazy.nvim. Also profile startup with --startuptime and trim autocommands — that’s where speed really shows. It made editing feel snappier for me, especially when juggling many plugins.

Okay, let me walk you through this like I'm showing a buddy at my desk — clipboard sync in "m vim" usually means getting Vim to talk to your system clipboard, and there are a few ways to make that happen depending on your OS and which Vim binary you're using.

First, check what your Vim actually supports: run :version inside Vim and look for +clipboard or -clipboard (or in Vim script do :echo has('clipboard')). If you already have +clipboard, the easy move is to add set clipboard=unnamedplus to your ~/.vimrc so the "+ register is used automatically. Then use "+y to yank or "+p to paste from the system clipboard.

If you see -clipboard, you probably need a different build. On macOS I usually install 'macvim' via Homebrew (brew install macvim) or the Homebrew 'vim' that includes clipboard support, and then make sure that binary is first in my PATH (which which vim will show). On Linux, install the GUI-enabled package like vim-gtk3 or vim-gnome (sudo apt install vim-gtk3). If you can't change the build, a hacky but reliable trick is mapping to system tools: for macOS use pbcopy/pbpaste (for example, vmap :w !pbcopy), on Linux use xclip/xsel, and on WSL use win32yank.exe or clip.exe. If you're in tmux or over SSH, look into OSC52 or tmux clipboard integration. Try these steps and see which one clicks for your setup — tell me what :version shows if you want more exact commands.

Oh man, marks in Vim are deceptively simple until you start mixing normal and visual mode — then they feel like a tiny secret language. In normal mode, hitting m followed by a letter (for example ma) sets a mark named 'a' at the exact cursor position. Lowercase letters a-z create buffer-local marks: they stick to that file and let you jump back with 'a (to the start of the line of the mark) or `a (to the exact column). If you use an uppercase letter like mA, you're setting a global mark: uppercase marks remember the file name too, so you can jump to that exact spot even from another buffer. One neat trick I use all the time is setting a mark before I start a risky refactor or a long move sequence, then using ` or ' to hop back. Also, marks can persist across sessions if you have viminfo configured to store them, which is lifesaving when a project spans days or weeks.

Visual mode is where folks sometimes get tripped up. Pressing m in visual mode still sets a mark at the cursor, but remember that the cursor in visual mode sits at one end of the selection. So if you select a block of text and the cursor is at the end, ma will put mark 'a' at that end — it doesn’t magically set both ends for you. For working with selections you’ll usually want to rely on the built-in visual marks '< and '>: these are automatically set to the start ('<) and end ('>) of the last visual selection and are super handy in commands. For example, :'<' , '>' yank will yank the last visual selection in ex mode. If you want a named bookmark for a selection, set a mark on one end with m and maybe another mark on the other end, or just use '< and '>. Jumping back to a visual boundary with `'< or `'> lands you exactly where the selection began/ended, which is unexpectedly satisfying when you’re juggling multi-line edits.

A few practical patterns I love: if I need to yank a region to reuse later across files, I’ll visually select the region, then set mark 'a at the start and mark 'b at the end (quickly with ma and mb), and then use :'a,'b y to yank that range into a register. Another favorite is using uppercase marks like mA before closing a file — I can reopen a different buffer and jump back to that spot anytime with 'A or `A. Also, remember the difference between ' (single quote) and ` (backtick): ' goes to the first non-blank of the marked line, ` goes to the exact column — that tiny distinction matters if you care about column positioning. Once you play with these a bit, m becomes less of a mystery and more of a tiny anchor that saves you from endless searching. If you want, I can run through a couple of short, concrete command sequences to show these tricks in action next.

Okay, here's a friendly walkthrough that helped me stop losing my place in files: press m followed by a letter to set a mark at the cursor. For example, ma sets mark 'a' right where the cursor sits. Lowercase letters (a–z) are local marks that live in the current file or buffer, which is great when I'm juggling long source files and want to bounce back to a function header.

To jump back I use 'a (single quote plus the mark letter) to move to the start of the marked line, or `a (backtick plus the mark letter) to jump to the exact column and line where I set the mark. That difference saved me once when I needed to return to the exact column inside a long JSON object — `a was the hero.

If I want to see what marks are set, I type :marks and it lists them. To remove marks I use :delmarks a or :delmarks a b c. Uppercase marks (A–Z) behave a bit differently — they record the file too so you can jump between files in the same session. Small tip: set useful short-named marks for spots you revisit often, like ma for a test stub and mb for a TODO comment; it's saved me tons of time.

Whenever I'm deep in a giant source file the 'm' command in Vim is my go-to little bookmark trick. Hit 'm' then a letter (for example 'ma') and Vim records the cursor position as mark 'a'. Lowercase letters a–z create marks that are local to the current file (buffer), so they help me jump around within that one document without affecting other files.

If I need to jump back, I use a backtick and the letter (for example ` `a` ) to go to the exact column and line, or a single quote and the letter (for example 'a) to jump to the start of that line. Uppercase letters A–Z store the filename too, so they act like global marks across files in the same Vim session — handy when I hop between multiple modules. You can list marks with :marks and remove them with :delmarks. Small tip: some environments also save marks across sessions if your config writes marks to viminfo, which means your bookmarks can survive a restart if you set it up right.

I love tinkering with editors, and I’ll say bluntly: yes, 'mvim' (MacVim) can open huge files, but whether it feels snappy depends on how you use it. On my MacBook, when I try to fling a 200MB log into MacVim with my full plugin stack and syntax highlighting on, it chokes — scrolling becomes stuttery, search gets slow, and the GUI redraws are the bottleneck. The trick is to treat huge files like special cases, not daily docs.

When I need speed I launch a bare session: vim -u NONE -N filename (or open MacVim with an equivalent minimal config). Once inside I flip off features that are expensive: :syntax off, :set noswapfile noundofile nowrap lazyredraw, and turn off folding and plugins that do realtime parsing. That instantly feels smoother. If I’m only grepping or viewing, I often use command-line helpers like head/tail/grep or split the file into chunks with split -l, edit the chunk, then stitch back together. For truly enormous files or binary blobs I’ll use specialized tools, but for plain text, MacVim with a pared-down runtime is surprisingly capable. It’s a small ritual for me now — treat the file with respect and you won’t regret opening it in 'mvim'.
