```

## 1 When typing long commands
* Edit command buffer `C-x C-e` like bash

## 2 When accidentally deleting more than wanted
* C-_ will undo last action
* zsh has a redo action

## 3
* magic-space
* `sudo !!` executes previous command from history
* caveat: we want to see what will be executed (like histverify)
* magic-space will expand history

## 4
+ chpwd hool: executes a command when we change dir
* example, in nixos will open a nix shell when cd'ing in
* example, when cd'ing into a virtual env
* can only define one chpwd hook

## 5
* `autoload -Uz add-zsh-hook`
* `add-zsh-hook chpwd nix_hook`
* `add-zsh-hook chpwd python_hook`
* `add-zsh-hook chpwd function() { ... }`

## 6
* auto open file
* suffix aliases -- run based on suffix
* `alias -s go='$EDITOR'`

## 7
* global aliases, can be used anywhere in a command
* `alias -g NE='2>/dev/null'`
* `du / NE` -- expands to `du / 2>/dev/null`
* define these with uppercase names

## 8 
* zmv
* autoload zmv
* `zmv '(*).log' '$1.txt'`
* `zmv -W '*.log' '*.txt'`
* `zmv -n ...` does dry run
* `zmv -i` will prompt for each change

## 9
* bookmarking locations
* `hash -d yt=~/Projects/youtube`
* `cd ~yt`

## 10
* zoxide

## 11
* customising actions for command line buffer
* widgets: functions that perform actions
* `zle` = zsh line editor

## 12
* configure hotkeys to insert into command buffer
* `bindkey -s '^Xgc' 'git commit -m ""\C-b'`
