1. Ctrl + F keys and a lot of other key combinations are hooked by MacOs. You're mostly don't use them, so just turn everything off in System Preferences -> Keyboard -> Shortcuts. If you have another software that handles your key combinations, like Keyboard Maestro, you should turn these actions/macros off, otherwise you won't get right hex sequence.

2. Enter command below in default MacOs Terminal. (Warning!: shortcuts can also be hooked by terminal emulators, like iTerm. To avoid it use default MacOs terminal. If you are on alacritty, you can enter alacritty --print-events and use poped up terminal).

xxd -psg

then type your key combination and hit enter. (Warning!: if you don't see any output for your combination, then read step 1 again)

Nerd Fonts for your IDE

https://www.nerdfonts.com/font-downloads

The following solution thanks to @hackerzgz & @snacky101 will install all nerd fonts;

brew tap homebrew/cask-fonts
brew search '/font-.*-nerd-font/' | awk '{ print $1 }' | xargs -I{} brew install --cask {} || true

Integralist

There are two 'types' to be aware of with a quickfix window:

1. entry: the actual line content (e.g. :grep foo will show a specific line that matched within a file).
2. file: the actual file itself (e.g. the path to the file that contained the match).

To replace content using vim (via the quickfix window) you need to choose whether you want to apply the change via the quickfix 'entry' or via the 'file' as a whole.

If you use cdo, then your 'action' (i.e. how you're going to replace content) will be applied to every entry in the quickfix window.

If you use cfdo, then your action will be applied to each file in the quickfix window.

Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

rust-play

#![allow(dead_code)]

// Suppose we have a shared context for a lot of values, in this specific case,
// this is a shared lua_State for lots of values which live in the lua registry.
struct Lua;

// This is a representation of a value that lives in that shared context.  In
// the real api, this is an enum that can represent any lua value, and most
// instances of it are handles to something that points to the lua registry,
// so logically it would hold a reference to the shared Lua state.

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.
