Close Session was bound to Ctrl+W by default. Ctrl+W is delete-word in every shell, readline prompt and agent CLI, so muscle memory killed the session (its tmux pane and CLI, with no confirm) mid-sentence, and with the split pane open it was not even the pane being typed in. Close Session now has no default key: the capture-phase handler lets Ctrl+W through and xterm sends ^W to whichever pane is focused. The action stays in the registry and can be bound in App Settings -> Shortcuts; the shortcut overlay shows it as not bound. The Help modal, CLAUDE.md, the split and tile-grid specs and three wiki pages stop advertising Ctrl+W as kill. Owner decision (tile-grid decision 5).

Keyboard Shortcuts
Every binding, and how to change them. Ctrl also accepts Cmd on macOS.
Press Ctrl+? in the app for the same list in a floating overlay.
Sessions and tabs
| Shortcut | Action |
|---|---|
Ctrl+K (also Cmd+K, Alt+K) |
Find an open session or start a new one. |
Ctrl+Tab |
Next session. |
Alt+[ / Alt+] |
Previous / next tab. |
Alt+1 to Alt+9 |
Switch to tab N. Physical keys, so macOS Option layouts work. |
Ctrl+Shift+{ / Ctrl+Shift+} |
Move the active tab left / right. |
Alt+B |
Collapse / expand the session sidebar, when that layout is on. |
Ctrl+W is not a Codeman shortcut: it goes to the terminal, where shells and agent CLIs
use it to delete the previous word. Close Session has no key by default; close a session
from its tab, or bind a key to it in App Settings → Shortcuts.
Terminal
| Shortcut | Action |
|---|---|
Enter |
Send. |
Shift+Enter |
Insert a newline without sending. |
Ctrl+Enter |
Same. |
Ctrl+C |
Copy the selection, or interrupt when nothing is selected. |
Ctrl+Shift+C |
Copy the selection. Never interrupts. |
Ctrl+V |
Paste. An image on the clipboard uploads and pastes its file path instead. |
Ctrl+L |
Clear the terminal. |
Ctrl+Shift+R |
Restore terminal size. |
Ctrl + / Ctrl - |
Font size. |
Shift+Wheel |
Scroll the local buffer, even where the wheel is forwarded to the CLI. |
Shift+drag |
Start a selection in a pane whose mouse events go to the CLI. |
| Right-click | Copy the selection. With nothing selected the native menu is left alone. |
Ctrl+Z |
Swallowed in agent sessions so a running CLI cannot be suspended. Normal job control in a shell. |
Anything you copy is cleaned on the way to the clipboard: each line loses the padding spaces a full-screen program paints across the rest of the row. Leading indentation is left exactly as it is, so indented code, a git log message body and git diff context lines paste back the way they looked on screen. An Alt+drag rectangular selection is copied exactly as it looks, so its columns stay lined up.
Everything else
| Shortcut | Action |
|---|---|
Ctrl+Shift+V |
Toggle voice input. |
Ctrl+? |
Shortcut reference overlay. |
Escape |
Close panels and modals. |
Rebinding
App Settings → Shortcuts. Bindings live in a registry with per-user overrides, so a rebind is stored as an override on top of the default rather than replacing the table.
Two things are deliberately not rebindable:
Ctrl+Csmart copy. The generic dispatch loop callspreventDefault()on every shortcut it handles, and doing that toCtrl+Cwould swallow the interrupt when nothing is selected. It is handled separately for that reason.Escape, which closes whatever is open.
Why some chords behave oddly
The terminal sees keystrokes before the app does. Any chord the app claims has to also be
swallowed at the terminal layer, or xterm writes the control byte into the session as well
as triggering the action. If you rebind something to a chord the terminal cares about
(Ctrl+D, say), expect the CLI to see it too.
Alt+1 through Alt+9 are matched on physical key position rather than the character
produced, so macOS Option layouts that produce ¡™£ still switch tabs.
On phones
There is no physical keyboard, so the equivalents live in the keyboard accessory bar: Esc,
Ctrl as a one-shot modifier, Tab, arrows, and quick actions. See
Mobile Guide.
