|
|
**Settings → Keyboard & Mouse → Keyboard shortcuts** (<kbd>⌘ ,</kbd>) lists every shortcut in the app,
|
|
grouped the same way the command palette is. The search box at the top of
|
|
Settings reaches this page too: type what a feature is called — `split`,
|
|
`commit`, `sftp` — and the page narrows to the shortcuts for it. Action names
|
|
work as well as labels, so a binding you read about in `keybindings.json` is
|
|
one search away from the row that sets it.
|
|
|
|
## Rebinding
|
|
|
|
Click a shortcut and press the new keys. It saves after a brief pause.
|
|
|
|
| | |
|
|
|---|---|
|
|
| Press keys | Set the binding |
|
|
| Press more keys | Chain a sequence — <kbd>⌃ B</kbd> then <kbd>X</kbd> |
|
|
| <kbd>Esc</kbd> | Cancel |
|
|
| <kbd>⌫</kbd> | Remove the last key — or, pressed first, leave the action with **no shortcut** |
|
|
|
|
Leaving an action unbound is how you hand a key back to whatever is running in
|
|
the terminal: <kbd>⌥ 1</kbd>…<kbd>⌥ 9</kbd> jump between tabs by default, and
|
|
vim wants them for its own tabs. Clear the nine **Go to Tab** rows and the
|
|
digits go straight through. A cleared row shows `—` and grows a **Reset**
|
|
button, which puts the default back.
|
|
|
|
**Restore all defaults** at the bottom undoes every rebinding at once. There is
|
|
no undo for that one.

|

|
## Actions with no default key
|
|
|
|
Some actions ship deliberately unbound, because there is no obvious key left to
|
|
take: pane resize and swap, workspace selection, most git commands, SFTP, and
|
|
the panel tabs. They are all in the command palette, and all bindable here.
|
|
|
|
## Editing `config.json` instead
|
|
|
|
```json
|
|
{
|
|
"keybindings": {
|
|
"NextTab": "cmd-shift-]",
|
|
"SplitRight": ["cmd-d"],
|
|
"ResizePaneLeft": "ctrl-alt-left",
|
|
"ToggleFullscreen": ""
|
|
}
|
|
}
|
|
```
|
|
|
|
An action's value takes one of two shapes:
|
|
|
|
| Value | Means |
|
|
|---|---|
|
|
| `"cmd-shift-]"` | **Add** this shortcut. The default keeps working — <kbd>⌃ ⇥</kbd> still switches tabs |
|
|
| `["cmd-d"]` | **Replace**: exactly these shortcuts, nothing else. List several to have several |
|
|
| `""` or `[]` | **Unbind** the action |
|
|
|
|
Recording a shortcut on the Settings page replaces, so it writes the list
|
|
shape. A shortcut you add that another action already uses is the one that
|
|
runs. The exception is the terminal's own shortcuts: copy, paste, find, clear
|
|
scrollback and insert newline keep theirs while a terminal has focus.
|
|
|
|
Up to 26.9.2 a string replaced the default, and the Settings page wrote
|
|
strings. So a shortcut you recorded in those versions now works *beside* the
|
|
default it was meant to replace. To drop the default again, record the shortcut again
|
|
or wrap it in a list: `"NewTab": ["cmd-shift-n"]`.
|
|
|
|
The syntax is modifiers joined by `-`, then the key. Chords are separated by a
|
|
space.
|
|
|
|
| Token | Means |
|
|
|---|---|
|
|
| `secondary` | <kbd>⌘</kbd> on macOS, <kbd>Ctrl</kbd> elsewhere |
|
|
| `cmd` · `ctrl` · `alt` · `shift` | Literal modifiers |
|
|
| `ctrl-b n` | A two-key sequence |
|
|
|
|
To keep a key for the program running in the terminal, unbind the action that
|
|
holds it. vim's tab keys, for instance:
|
|
|
|
```json
|
|
{
|
|
"keybindings": {
|
|
"ActivateTab1": [], "ActivateTab2": [], "ActivateTab3": [],
|
|
"ActivateTab4": [], "ActivateTab5": [], "ActivateTab6": [],
|
|
"ActivateTab7": [], "ActivateTab8": [], "ActivateTab9": []
|
|
}
|
|
}
|
|
```
|
|
|
|
An unknown action name, an invalid keystroke, or a line that is neither a
|
|
shortcut nor a list of them is skipped with a warning in the log rather than
|
|
breaking the rest of your bindings.
|
|
|
|
The full action list is on the [keyboard shortcuts](/reference/keyboard-shortcuts)
|
|
page.
|
|
|
|
## The tmux preset
|
|
|
|
**Settings → Keyboard & Mouse → Keyboard shortcuts → Preset → tmux** remaps pane and tab actions onto a
|
|
prefix — <kbd>⌃ B</kbd> by default, changeable in the **Prefix** field beside
|
|
it.
|
|
|
|
| | |
|
|
|---|---|
|
|
| <kbd>⌃ B</kbd> <kbd>C</kbd> · <kbd>X</kbd> | New tab · close tab |
|
|
| <kbd>⌃ B</kbd> <kbd>%</kbd> · <kbd>"</kbd> | Split right · split down |
|
|
| <kbd>⌃ B</kbd> <kbd>←→↑↓</kbd> | Move focus |
|
|
| <kbd>⌃ B</kbd> <kbd>⌃ ←→↑↓</kbd> | Resize the pane |
|
|
| <kbd>⌃ B</kbd> <kbd>O</kbd> · <kbd>;</kbd> | Next pane · previous pane |
|
|
| <kbd>⌃ B</kbd> <kbd>{</kbd> · <kbd>}</kbd> | Swap with the previous · next pane |
|
|
| <kbd>⌃ B</kbd> <kbd>Z</kbd> | Zoom the pane |
|
|
| <kbd>⌃ B</kbd> <kbd>N</kbd> · <kbd>P</kbd> | Next tab · previous tab |
|
|
| <kbd>⌃ B</kbd> <kbd>1</kbd>…<kbd>9</kbd> | Jump to a tab |
|
|
|
|
Two details that make it livable:
|
|
|
|
- A **bare prefix** reaches the shell after about a second, so <kbd>⌃ B</kbd>
|
|
still works as "back one character" when you meant it.
|
|
- **Prefix plus an unbound key** is passed straight through to the terminal, so
|
|
a tmux binding you did not remap still lands in whatever is running.
|
|
|
|
## Some non-obvious defaults
|
|
|
|
| | |
|
|

|
|
| <kbd>⇧ ⏎</kbd> · <kbd>⌥ ⏎</kbd> | Insert a newline at the prompt instead of submitting (`InsertNewline`) |
|
|
| <kbd>⌘ ⇧ ⏎</kbd> | Zoom the focused pane |
|
|
| <kbd>⌘ ⇧ E</kbd> | Toggle the code panel |
|
|
| <kbd>⌘ ⇧ R</kbd> | Restart the SSH session in this pane |
|
|
| <kbd>⌘ ⇧ O</kbd> | Workspace switcher |
|
|
| <kbd>⌘ ⇧ N</kbd> | New workspace |
|
