Keyboard shortcuts

Every key, click and gesture the app answers to, from the list the app itself draws.

Made from the list the app's own Keys and controls panel draws (F1 or , in the app), and from the menus' keys, so it says exactly what the app answers to.

These are the app's own keys. To use BrickLink Studio's, Mecabricks' or LDCad's instead, or to set your own, see Your own keys.
