TMUX

TMUX Cheat Sheet

I setup TMUX to work with nvim using vim-tmux-navigator, so my defaults for moving left, right, up, and down are vim defaults.

Start tmux using tmux
Think of windows as “screens” and panes as tabs
Start tmux with name using tmux new -s name
List tmux sessions: tmux ls
Attach to a session: tmux a #
Attach to a named session: tmux a -t name
Kill a session: tmux kill-session -t name
Kill tmux server: tmux kill-server
Use Ctrl+hjkl to switch between panes
Press Ctrl-a to prefix tmux keyboard shortcuts (remapped)
% to split screen horizontally
" to split screen vertically
d to detach (leaving it running in background)
x to kill current pane
? to list all keybindings
{ move current pane left
} move current pane right
o go to next pane
z toggle full-screen mode for current pane

Vim

Use i to do an action within a motion
- e.g. ciw to change the word
Use c to change within motion
Use p to denote paragraph
Use :set to access or modify values
- Append option with ? to see the current value
Buffers: an open file in memory
- Three states:
  - Active: buffer is displayed in a window
  - Hidden: buffer exists, but is not displayed
  - Inactive: buffer is not displayed and does not link to a file
- :buffers or :ls to list all the current buffers
  - Displays buffer ID, state, name, and cursor line
  - Hidden buffers won’t be displayed, either set hidden or append ! to command
- Most buffer commands start with :b
  - :bn to move to next buffer
  - :bp to move to previous buffer
  - :bf to move to first buffer
  - :bl to move to last buffer
  - Ctrl-^ to switch to alternate buffer
  - Run command on all buffers: :bufdo <command>
  - Use :b <name> to switch to buffer with name using partial name matching
- Create and delete buffers:
  - :badd <filename> adds <filename> to the buffer list
  - :bdelete <ID_or_name> deletes all buffers in <ID_or_name>
  - :%bdelete deletes all buffers
Windows: where vim can display the content of a buffer
- To create a new window use :new
  - CTRL-W s to split the current window horizontally
  - CTRL-W v to split the current window vertically
  - CTRL-W n to split the current window horizontally and edit a new file
  - CTRL-W ^ to split the current window with the alternate file (buffer with # indicator)
  - <buffer_ID>CTRL-W ^ split current window with <buffer_ID>
- To switch between windows:
  - CTRL-W CTRL-W to switch to last (alternate?) window
  - CTRL-<hjkl> to move left, down, up, or right (remap)
- To rotate windows:
  - CTRL-W r rotate the windows
  - CTRL-W x exchange with next window
- To resize windows:
  - CTRL-W = resize windows to fit on screen with the same size
  - CTRL-W + increase window height
  - CTRL-W - decrease window height
  - CTRL-W < decrease window width
  - CTRL-W > increase window width
- Exit windows with :q or :q! (these commands don’t quit vim, but quit a window!)
To edit a new file use :e

Lua + Neovim

Lua basics: honestly pretty similar to JS/Python
comments are --, multi-line is two brackets [[comment here]]
use if condition then for if statements
- finish if statements with end
blocks use do/end
not equals is: ~=
finish functions with end after return
most everything else is either unimportant for what I care about right now, or something I’ll google
Neovim lua config:
To edit global settings, use the global variable/module vim
- i.e. vim.opt.option_name = value
lua/plugins.lua contains the config file for loading plugins
