kill9 is built for keyboard use. Most actions have a shortcut, and the ones you use most often become muscle memory quickly.
Navigation
Cmd/Ctrl+K opens the command palette. This is the fastest way to do almost anything — search for surfaces, run commands, or find settings. Think of it as Spotlight or Alfred for kill9.
Mod+1 through Mod+7 switches between the seven workspace rail surfaces. Mod+1 is Inbox, Mod+2 is Work, Mod+3 is Plan, Mod+4 is Docs, Mod+5 is Mockups, Mod+6 is Review, and Mod+7 is Tools.
Cmd/Ctrl+I opens Inbox directly, even if you're in another surface.
Cmd/Ctrl+Shift+A opens the Agents browser where you can browse and customize agents.
Cmd/Ctrl+, opens Settings.
Panels and layout
Cmd+D splits the currently focused pane horizontally. This is how you keep multiple surfaces visible at once — Work on the left, Browser on the right, for example.
Ctrl+Shift+Z toggles Zen Mode, hiding the workspace rail and other chrome for focused work.
Contextual shortcuts
Some shortcuts only work in specific contexts. The inspector in the Browser panel has its own shortcuts. The editor has shortcuts for formatting and navigation. The chat composer sends on Enter and creates a new line on Shift+Enter.
Customization
Open Settings (Cmd/Ctrl+,) and go to the Shortcuts section to customize any shortcut. Click a shortcut, press the new key combination, and it updates immediately.
