Press Cmd-K (or Ctrl-K on Windows and Linux) anywhere in the app and a search box opens over the page.
Start typing and the palette filters as you go. Type a destination name to jump to it: search, companies, lists, exports, verify, billing. Use the arrow keys to move through results and Enter to go. Esc closes the palette and leaves the page underneath untouched.

The palette is the fastest path through a normal working session. A typical loop looks like this: Cmd-K to People, build a segment, Cmd-K to Lists to save it, Cmd-K to Exports to pick up the CSV when it finishes. You never need to hunt for the sidebar item, and it works the same on every page.
Two habits make it worth the muscle memory. First, use it instead of the browser back button, which can drop you out of a half-built filter set. Second, use it while an export is processing: you can leave the export page, keep searching, and come back later without interrupting anything. Large exports run in the background regardless of where you are.
Nothing in the palette spends credits. It is navigation only.
