Vim

I use vim as my editor and have customized it a bunch. Note that <g-j> means to press g and j simultaneously. I generally run vim from the root of a project directory.

Shortcuts

General

Normal and insert mode

  • <ctrl-s> saves the file. If in insert mode, it exits insert mode first. This is basically always how I exit insert mode.

Normal mode

  • } moves forward to the next blank line. I use this all the time
  • { moves backward to the prev blank line. I use this all the time
  • <g-j> k opens a file from the current directory, allowing you to search using fzf. With a file selected, press
    • <enter> to open the file in the current window
    • <ctrl-v> to open the file in a new vertical split
    • <ctrl-x> to open the file in a new horizontal split
  • <g-j> j allows you to select an already open buffer using fzf. The same shortcuts as above will work.
  • ga searches all files in the currenty directory and displays the results using fzf. You can select a result to open that in a buffer.
  • <shift-q> quits vim
  • gr reloads the current file
  • <ctrl-n> selects the word under the cursor. Pressing it again also selects the next instance of that word. You can keep pressing to select more instances of that word. Then you can press keys (eg s) to work on all these instances at the same time. See vim-multiple-cursors for more info.
  • gw <motion> breaks lines automatically. It's built-in, but I use it all the time.
  • = <motion> automatically fixes indentation. Also built-in, but really useful.
  • gs <motion> sorts lines or words across <motion>
  • <g-j> n lets you create a new file in the same directory as the current buffer.
  • <shift-q> closes the current window, quitting vim if it's the only window open.
  • gn clears the current highlighting
  • <shift-8> searches forwards for instances of the word under the cursor
  • <shift-3> searches backwards for instances of the word under the cursor
  • . repeats the last action. I use this all the time
  • q<key> records a macro. This is great. Look up "vim macros" and learn to use them.

Insert mode

  • <ctrl-x> <ctrl-f> when your cursor is at the end of a word will allow you to select a file using fzf to insert at current position in buffer.
Window management
  • <g-j> <space> switches windows

ctags

ctags is a really useful tool for navigating files. It tracks all the function and class declarations in all your files, and lets you search for them and jump to them.

Normal mode

  • gt opens a list of tags in fzf.
  • <g-j> f finds the tag corresponding to the word under your cursor
  • <g-j> ; jumps back to where you were after finding the tag under the cursor
  • <g-j> o opens a sidebar which shows you all the tags in the current file. See tagbar for more info.

Python

Normal mode

  • <g-j> i sorts imports
  • <g-j> a puts function arguments on multiple lines, or back on a single line. This is fantastic. Use it.
  • gb swaps a function argument with the next one
  • gB swaps a function argument with the previous one
  • The ii motion applies to the current indent level. See doc

Other

Take a look in dotConfig/nvim/config/maps.vim to find more shortcuts. There are definitely others I use.
