Command Bar (Cmd-K)
Definition: A keyboard-driven launcher for navigation, search, and actions — typically opened with ⌘K or Ctrl+K.
What it is
The command bar (often called Cmd-K after its shortcut) is a power-user UI primitive popularized by Linear, Superhuman, and Notion. It opens an overlay where users can navigate to any record, run any action, or search any content from the keyboard — without ever using a mouse. Command bars dramatically increase advanced-user throughput.
Why it matters
Teams that use a Cmd-K-first workspace report meaningful productivity gains — every navigation that would have been a 3-click mouse path becomes 4 keystrokes.
Layer UI in context
Layer UI ships a Cmd-K command bar from day one — search, navigate, create a task, message a teammate, all from the keyboard.
