Hold Caps Lock and a keyboard appears: every shortcut you've bound in the app you're in, on the key it lives on. Press it, it runs. Open an app, press keys, paste a snippet, click a button, run a script: one key each. Shortcuts know which app, site or window you're in, so one key means different things in Gmail and in your CRM. Runs on your Mac, works offline, voice transcribed on-device. For most people it replaces Raycast or Alfred. Free up to 20 shortcuts; Pro $12/month.
