These are the default bindings. Choose the scheme and change any binding in Preferences > Controls (Ctrl+,);
the in-app shortcut sheet (Shift+F1) always shows the keys you actually use.
- Hold Shift while placing or dragging to free the grid and the snaps; hold Alt to free the angle of a wall,
railing or flight.
- F3 searches every command by name when you cannot remember a key.
- A dash (—) means no key by default; bind one in Preferences if you want it.
