Keys follow Micro; [every key](keys) has a list.

| Key | Does |
|---|---|
| Shift + arrows, mouse drag | select |
| Ctrl-A | select all |
| Ctrl-C / Ctrl-X / Ctrl-V | copy / cut / paste (no selection: the whole line) |
| Ctrl-Z / Ctrl-Y | undo / redo |
| Alt-Up / Alt-Down | move lines |
| Ctrl-Shift-D | duplicate the line |
| Tab / Shift-Tab | indent / outdent |
| Alt-/ or Ctrl-/ | comment or uncomment lines |
| Ctrl-] | jump to the matching bracket |
| Alt-O / Alt-I | grow / shrink the selection by syntax |
| Ctrl-U | start / stop recording a macro (● REC in the status line) |
| Ctrl-J | replay the macro |

## Typing helps

- Brackets and quotes close themselves; typing the closer steps over it, and Backspace between an empty pair deletes both. With a selection they wrap it. Quotes don't pair inside words. Off with `"autoclose": false`.
- Enter after `(` `[` `{` indents and puts the closer on its own line.
- Tab inserts the file's own indentation (tabs or spaces, detected). `"tabstospaces": true` picks spaces for new files.
- The cursor moves over whole characters as you see them: emoji, accented letters, flags.

## Lines and case

`:JoinLines` `:SortLines` `:UpperCase` `:LowerCase` `:TitleCase` `:TrimTrailingWhitespace` work on the selection (case: the word at the cursor), at every cursor, as one undo step.

## Undo history

Undo survives closing a saved file and quitting, as long as the file didn't change on disk in between (2 MB per file, 32 MB in all, in the state folder).

## Scrolling

The wheel scrolls lines; Shift+wheel or a sideways swipe scrolls long lines until the cursor moves.

> [!NOTE]
> Without the kitty keyboard protocol some terminals send Ctrl-] as Ctrl-5 and Ctrl-Shift-D as Ctrl-D. Bind another key in bindings.json, for example `{"Ctrl-5": "JumpToMatchingBrace"}`, or use the [typed command](typed).
