Keybindings

Settings → Keybindings. Two sections — Editor and Agentic chat — showing the app's shortcuts and letting you change most of them.

Rebinding#

Click the shortcut, then press the new keys. The chip reads Press keys… while it's listening, and every keystroke is captured rather than acted on, so you can't accidentally trigger something mid-rebind.

Escape cancels, and so does clicking anywhere else.

Your combination must include Ctrl (or Cmd) or Alt. A bare letter or function key is rejected and the chip keeps waiting — these are global bindings, and a bare key would hijack typing everywhere.

If the combination is already used by another shortcut on this page, nothing is saved and the row tells you which one has it: Already used by "Toggle terminal". If it's a combination your browser or OS normally owns — Ctrl+W, Ctrl+R, Ctrl+Q and friends — an amber ⚠ names the clash but the binding is saved. That's a judgement call left to you.

A small reset arrow appears at the left of any row you've changed, to put it back. There's no reset-all.

What you can rebind#

Everything in this group is driven by this page, and takes effect immediately.

Shortcut	Row	Does
Ctrl+J	Toggle terminal	Show/hide the bottom panel
Ctrl+Shift+F	Open search	Open the Search panel and focus its box
Ctrl+,	Open settings	Open Settings, or jump to it if it's already open
Ctrl+B	Toggle Explorer	Show/hide the explorer panel
Ctrl+Shift+A	Toggle Agent panel	Show/hide the agent panel (does nothing in runs mode)
Ctrl+Shift+G	Toggle Navigation	Show/hide the graph's navigation dial and camera buttons
F11	Full screen (Esc also exits)	Full screen; the panels stay as they were
Ctrl+T	New chat	Start a new conversation
Ctrl+Tab / Ctrl+Shift+Tab	Next / Previous chat tab	Cycle conversations
Ctrl+Shift+→ / Ctrl+Shift+←	Next / Previous chat tab (alt)	The same, second binding
Ctrl+Shift+↓ / Ctrl+Shift+↑	Minimize / Restore all run cards	Runs mode only

What you can't#

These appear on the page greyed out, with the tooltip Not remappable yet. They work; they just can't be changed.

Shortcut	Does
Ctrl+S	Save the open file
F2	Rename the focused item in the explorer
Delete	Delete the selected explorer items
Enter	Open the focused file or folder in the explorer
Ctrl+←/→/↑/↓	Snap the active floating window to a half of the screen
Ctrl + / -	Zoom the interface and editor fonts together
Ctrl+1–9	Jump to chat tab N (9 is always the last)
Space Space	Collapse/expand the runs-mode command bar
Enter	Send the chat message (Shift+Enter for a newline)
Escape	Stop the agent

Shortcuts that aren't on this page at all#

This is the part worth reading, because the page looks like a complete list and isn't. All of these work, none of them appear there, and none can be rebound.

(Enter and Escape do appear on the page — but only for sending, opening a file, and stopping the agent. The other jobs they do below are listed nowhere.)

In the editor

Shortcut	Does
F12	Go to definition
Ctrl+F	Find in this file
Ctrl+G / Shift+Ctrl+G, F3 / Shift+F3	Find next / previous
Ctrl+Z / Ctrl+Y	Undo / redo (Ctrl+Shift+Z also redoes on Linux, ⌘⇧Z on macOS)
Ctrl+/	Toggle comment
Ctrl+D	Select the next occurrence
Ctrl+Shift+L	Select all matches
Alt+↑ / Alt+↓	Move the line up / down
Shift+Alt+↑ / Shift+Alt+↓	Copy the line up / down
Ctrl+Alt+↑ / Ctrl+Alt+↓	Add a cursor above / below
Ctrl+Shift+K	Delete the line
Ctrl+[ / Ctrl+]	Outdent / indent
Ctrl+Alt+G	Go to line
Tab	Expand an Emmet abbreviation, or indent

In the explorer — Ctrl+C, Ctrl+X, Ctrl+V copy, cut and paste files and folders.

Over the 3D view — Escape first cancels a highlight in progress, then closes the open node card, and only then leaves full screen.

In the chat composer (desktop app only) — Ctrl+Z undo, Ctrl+Shift+Z or Ctrl+Y redo, Ctrl+Shift+←/→ extends the selection by a word, Ctrl+Shift+↑/↓ by a line.

Everywhere — Escape closes menus, dropdowns, dialogs, the image viewer and the project picker; ↑ ↓ Enter Escape drive the search panel and inline rename fields.

Things that will look like bugs#

Ctrl+O does nothing. The project chip's menu shows Open Project with Ctrl+O next to it, but there's no shortcut behind it. Use the menu item.

The menu bar doesn't follow your rebinds. The shortcut in each icon's tooltip is fixed text. Rebind Toggle Explorer to something else and the Explorer panel tooltip still says Ctrl+B forever.

On Linux, the Super key also triggers everything. Every Ctrl+… shortcut here answers to Super+… as well. If a shortcut fires when you meant to do something with your window manager, that's why.

The terminal eats almost every Ctrl shortcut. Ctrl+J is the only combination it hands back to the app — so that the toggle keeps working while you're in it, at the cost of never being able to send a literal Ctrl+J to a program running there. Everything else that maps to a control character — Ctrl+B, Ctrl+T, Ctrl+S — belongs to the terminal while it has focus and never reaches Semantix, rebound or not.
