| 1 | # Keybindings |
| 2 | |
| 3 | Customize shortcuts in **Settings → Keybindings** on web and desktop. That page |
| 4 | also lists the command IDs and defaults available in your version. |
| 5 | |
| 6 | ## Composer controls |
| 7 | |
| 8 | In **Settings → General → Send shortcut**, choose whether Enter sends, requires |
| 9 | `mod+Enter` for multiline prompts, or always requires `mod+Enter`. `Shift+Enter` |
| 10 | inserts a new line. This applies to the web and desktop composer at desktop widths. |
| 11 | |
| 12 | **Follow-up behavior** chooses Queue or Steer while the agent runs. Use |
| 13 | `mod+Enter` to do the opposite for one message, even when the send shortcut |
| 14 | requires a modifier. `mod+Alt+Enter` sends, keeps that thread running in the |
| 15 | background, and opens a fresh new-thread composer. In a new thread, `mod+Enter` |
| 16 | does the same. Change these shortcuts in **Settings → Keybindings** under |
| 17 | **Composer: Opposite Queue or Steer Action**, **Composer: Start in Background**, |
| 18 | or **Composer: Send and Start New Thread**. These bindings take priority over the |
| 19 | send shortcut. Click the send button to use the configured follow-up behavior. |
| 20 | |
| 21 | When an active turn has queued messages, `mod+Shift+Enter` sends the first as a |
| 22 | steer. Change it under **Queue: Send First Queued Message as Steer** in Keybindings. |
| 23 | |
| 24 | Use `mod+shift+m` to choose a model and `mod+shift+h` to choose a host. |
| 25 | To step a new thread to the next machine instead of opening the menu, bind |
| 26 | **Composer: Cycle Host** in Keybindings. It has no default shortcut. |
| 27 | Use `mod+shift+e` for effort, `mod+shift+a` for access mode, `mod+shift+x` for the |
| 28 | workspace, and `mod+shift+g` for the Git branch. The workspace menu includes the |
| 29 | current checkout, a new worktree, and the previous worktree when available. |
| 30 | Use `mod+shift+l` to reuse the previous worktree directly. |
| 31 | |
| 32 | In the model picker, press Left in an empty search field or Shift+Tab to reach |
| 33 | the provider list. Use Up/Down to move and Enter to choose. Right returns to |
| 34 | model search. `mod+shift+up` and `mod+shift+down` switch providers directly and clear the |
| 35 | search. These provider shortcuts can also be changed in Settings. |
| 36 | |
| 37 | These shortcuts run inside the focused web or desktop client. `mod` uses Command |
| 38 | on macOS and Ctrl on Windows and Linux, including GNOME, KDE Plasma, Niri, and |
| 39 | Hyprland. If a custom desktop shortcut takes the same keys, choose another binding |
| 40 | in Settings. |
| 41 | |
| 42 | ## Copy pull request references |
| 43 | |
| 44 | With a PR open in the right panel or on the Pull Requests page, use `mod+shift+c` |
| 45 | to copy its URL and `mod+shift+k` to copy its number with a `#` prefix. |
| 46 | Both shortcuts can be changed in Settings. Search for “Copy Link or Thread ID” |
| 47 | or “Copy Number”. They copy the selected PR and leave terminal input alone. |
| 48 | |
| 49 | ## Find in a diff |
| 50 | |
| 51 | Click into a diff in the Diff panel or a pull request's Code tab, then press |
| 52 | `mod+f` to search every file in it, including folded files and unchanged lines |
| 53 | hidden between changes. Enter and `Shift+Enter` move between matches, and a |
| 54 | match in a folded file opens it. Escape closes the search. This shortcut is not |
| 55 | configurable. A very large uncommitted diff loads its files as you scroll, and |
| 56 | find only searches the files loaded so far. |
| 57 | |
| 58 | ## iPad |
| 59 | |
| 60 | With a hardware keyboard, use `Cmd+1` through `Cmd+9` to open the first nine |
| 61 | displayed threads. The shortcuts follow the current list filters and order. |
| 62 | `Cmd+K` opens the command palette to search commands, projects, and threads. |
| 63 | Use the arrow keys and Return to choose a result, or `Cmd+1` through `Cmd+9` to |
| 64 | choose directly. Escape or `Cmd+K` closes the palette. Start a search with `>` |
| 65 | to show only actions. |
| 66 | |
| 67 | In a new thread, `Cmd+Shift+H` moves the draft to the next machine. |
| 68 | |
| 69 | In the composer, Return sends and `Shift+Return` inserts a new line. `Cmd+Return` |
| 70 | also sends. To make Return insert a new line instead, change the Return key |
| 71 | behavior in Settings → Keyboard. |
| 72 | |
| 73 | ## Edit the configuration file |
| 74 | |
| 75 | Keybindings live on the environment's machine, in |
| 76 | `~/.t3/userdata/keybindings.json` by default. You can edit this file directly. |
| 77 | It is a JSON array of rules: |
| 78 | |
| 79 | ```json |
| 80 | [ |
| 81 | { "key": "mod+g", "command": "terminal.toggle" }, |
| 82 | { "key": "mod+shift+g", "command": "terminal.new", "when": "terminalFocus" } |
| 83 | ] |
| 84 | ``` |
| 85 | |
| 86 | T3 Code creates the file with its defaults and adds new defaults on later startups. |
| 87 | New defaults do not replace commands you customized. If a new default overlaps one |
| 88 | of your shortcuts, [rule order](#precedence) decides which runs. |
| 89 | Invalid rules are ignored; if the file cannot be parsed, T3 Code uses defaults. |
| 90 | |
| 91 | ## Rule shape |
| 92 | |
| 93 | Each rule requires a `key` shortcut and a `command` ID. An optional `when` |
| 94 | expression restricts when it runs. |
| 95 | |
| 96 | Project scripts use `script.{id}.run`, such as `script.test.run`. |
| 97 | |
| 98 | ## Key syntax |
| 99 | |
| 100 | Join modifiers and a key with `+`, such as `mod+shift+d` or `ctrl+l`. |
| 101 | `mod` means Command on macOS and Control elsewhere. Other modifiers are |
| 102 | `cmd` / `meta`, `ctrl` / `control`, `alt` / `option`, and `shift`. |
| 103 | |
| 104 | ## When conditions |
| 105 | |
| 106 | Available context keys are `terminalFocus`, `terminalOpen`, `previewFocus`, |
| 107 | `previewOpen`, `modelPickerOpen`, `usagePageOpen`, `composerFocus`, `composerDraft`, |
| 108 | `turnRunning`, `editableFocus`, `isWeb`, and `isDesktop`. |
| 109 | `editableFocus` is true while a text field, the composer, or another editor has |
| 110 | the keyboard. `isWeb` is true in a browser tab. `isDesktop` is true in the |
| 111 | desktop app. Unknown keys evaluate to `false`. |
| 112 | |
| 113 | `mod+1` through `mod+9` jump to the first nine threads, and to models while the |
| 114 | model picker is open. The thread jumps do not run while the model picker is open. |
| 115 | Those defaults use `isDesktop` so they do not steal the |
| 116 | browser's tab-switch shortcuts. Remove that condition in Settings if you want |
| 117 | the same jumps in a browser. |
| 118 | |
| 119 | Combine keys with `!` for not, `&&` for and, `||` for or, and parentheses: |
| 120 | |
| 121 | ```json |
| 122 | { "key": "mod+j", "command": "terminal.toggle", "when": "terminalOpen && !terminalFocus" } |
| 123 | ``` |
| 124 | |
| 125 | ## Find in the current thread |
| 126 | |
| 127 | `chat.find` searches conversation messages and proposed plans in the active thread. Entering a |
| 128 | query searches the entire thread, including older messages. Thread search requires server support; |
| 129 | update an older server to enable it. Select **Retry** if a search fails. It defaults to |
| 130 | `mod+f` outside terminals and previews. Press **Enter** or **Shift+Enter** to move between matches, |
| 131 | and **Escape** to close find. |
| 132 | |
| 133 | ## Precedence |
| 134 | |
| 135 | The last rule whose key and condition both match wins, even if it belongs to a |
| 136 | different command. Put a more specific rule after a general one when they share |
| 137 | a shortcut. |
| 138 | |
| 139 | ## Commands with special behavior |
| 140 | |
| 141 | `thread.stop` interrupts the running turn in the focused thread. It has no default |
| 142 | shortcut; assign one in **Settings → Keybindings**. |
| 143 | |
| 144 | `thread.undo` (`mod+z` by default) reverses the actions shown in the notice at the |
| 145 | bottom of the sidebar, such as unpin, settle, snooze, archive, or discarding a |
| 146 | draft. Consecutive |
| 147 | actions of the same kind undo together. The notice remains available for five |
| 148 | seconds after the latest action. The default shortcut skips text fields and |
| 149 | terminals so native undo keeps working there. |
| 150 | |
| 151 | `navigation.back` (`mod+[` by default) and `navigation.forward` (`mod+]`) move |
| 152 | through the pages you have visited, like a browser's back and forward buttons. |
| 153 | |
| 154 | `chat.new` may ask you to choose a project when there is more than one. |
| 155 | `chat.newLocal` skips that chooser. Both use your |
| 156 | [new-thread defaults](./thread-sidebar.md#start-a-thread). `chat.newWithoutProject` |
| 157 | (`mod+alt+n`) starts a thread [without a project](./thread-sidebar.md#start-without-a-project). |
| 158 | |
| 159 | ## Reserved shortcuts |
| 160 | |
| 161 | In the desktop app, `mod+w` closes the focused terminal or the active right-panel |
| 162 | tab. When nothing remains to close, it closes the window. In a browser, `mod+w` |
| 163 | closes the browser tab; rebind `rightPanel.close` and `terminal.close` to an available |
| 164 | shortcut such as `alt+w`. |
| 165 | |
| 166 | `mod+shift+t` reopens the last closed tab across the app, including files, |
| 167 | diffs, pull requests, browsers, and devices, in the order you closed them. |
| 168 | A browser opens in a fresh session without its old page history. Incognito tabs |
| 169 | can reopen until you reload or quit the app. This shortcut does not undo deleted work. |
| 170 | Browsers also use it to reopen browser tabs; choose another binding in Settings |
| 171 | if the browser takes it first. |
| 172 | |
| 173 | Many defaults include `!terminalFocus` so they do not intercept terminal input. |
| 174 | Keep that condition when remapping them if you want the same behavior. |
| 175 | |
| 176 | ## Desktop quit shortcut |
| 177 | |
| 178 | Use `Cmd+Q` on macOS or `Ctrl+Q` on Windows and Linux. In the default **Hold** mode, |
| 179 | hold for 1.2 seconds or press twice within 500 milliseconds. Holding requires |
| 180 | keyboard repeat; if repeat is disabled, use two presses or the application menu. |
| 181 | |
| 182 | Change **Settings → General → Confirmations → Quit shortcut** to **Direct** for a |
| 183 | single press or **Double press** for two presses only. Choosing **Quit** from the |
| 184 | application menu always quits immediately. |
