  81 # Rebinding keys
  82
  83 The bindings may be rebound using the `~/.config/micro/bindings.json`
  84 file. Each key is bound to an action.
  85
  86 For example, to bind `Ctrl-y` to undo and `Ctrl-z` to redo, you could put the
  87 following in the `bindings.json` file.
  88
  89 ```json
  90 {
  91         "CtrlY": "Undo",
  92         "CtrlZ": "Redo"
  93 }
  94 ```
  95
  96 You can also chain commands when rebinding. For example, if you want Alt-s to save
  97 and quit you can bind it like so:
  98
  99 ```json
 100 {
 101     "Alt-s": "Save,Quit"
 102 }
 103 ```
