Almost everything in Lightworks can be driven from the keyboard, and almost every key can be reassigned. The Keyboard Shortcuts panel (in the Settings menu) is where you view, change, and extend the keyboard - including building macros that run several commands from one key.
The panel lists every available command with its Command, Category, and assigned Key columns, and every command carries a description. Use the search to find a command by name - it's the fastest way to answer "is there a key for this?".
Keys are shown the way they appear on the keyboard: single letters as capitals, Shift-modified letters as Shift+N, and the macOS Command key as Cmd.
A command can have more than one key, and Lightworks warns you when a key is already in use so you don't silently steal a binding you rely on.
A macro runs a sequence of commands with a single press:
Macros shine for repetitive sequences - a save-and-export chain, a trim-and-play pattern, or setting up marks the same way on every clip. Edit or delete macros from the same panel.
The default key assignments for editing, trimming, playback, and navigation are covered in their subject articles - see Basic editing, Trimming, and Keyboard shortcut tables for the full listing.
Tip: Change defaults sparingly and export your setup when you do. A heavily customised keyboard is powerful but makes tutorials, documentation, and other people's machines harder to follow.
