Keyboard shortcuts

Voxel Mode binds 55 keyboard shortcuts. Every one of them can be changed in Edit ▸ Preferences ▸ Add-ons ▸ Voxel Mode ▸ Keyboard Shortcuts: click a row, press the new key, and Backspace removes a binding. See Customising shortcuts.

The Works in column matters. Blender checks the mode’s own keymap before an add-on’s, so a key only overrides Blender’s meaning where the table says it does. Everywhere else the key does what Blender normally does.

Mouse

Mouse bindings are fixed. They are not in the preferences table, because rebinding the plain left click would leave you with no way to draw.

Active tool	Click	Shift + click	Ctrl + click
Attach	Attach voxels	Erase voxels	Paint (primary colour)
Erase	Erase voxels	Attach voxels	Paint (primary colour)
Paint	Paint (primary colour)	Paint (secondary colour)	Attach voxels

With any brush	Does
Alt + click	Pick the colour under the cursor
Shift + Alt + click	Draw on the grid’s side walls
Ctrl + Alt + click	Switch to the model under the cursor

Inside a move, rotate or scale

While a transform is running, its own keys apply. These are fixed, not in the preferences table.

Key	Move (G)	Rotate (Shift+R)	Scale (S)
X / Y / Z	Lock to that axis	Turn about that axis	— (scale is uniform)
Arrow keys	Nudge one voxel along the screen	← / → quarter turn	↑ / ↓ one voxel bigger or smaller
Page Up / Page Down	Nudge away / nearer	—	—
End	Drop onto whatever is below	—	—
G / R / S	Switch to move, rotate or scale without cancelling
Click or Enter	Confirm	Confirm	Confirm
Esc or right-click	Cancel: everything goes back	Cancel	Cancel

Middle mouse and the wheel keep orbiting and zooming mid-drag. For an exact distance, use Move Selection (typed), Shift + G.
