Workflow Shortcuts
Lumi-o is built for a shortcut-driven workflow. Once you establish muscle memory for these commands, you can navigate your canvas and tools significantly faster.
Essential Canvas Controls
| Action | Shortcut |
|---|---|
| Adjust Brush Size | Alt + Right Click & Drag |
| Cycle Select Layers | Alt + Hover over canvas |
Tip: Alt Key Conflict on Linux
If Alt + Right Click Drag does not resize brushes in Lumi, the desktop is using Alt for window management.
- Search the system menu for Windows.
- Windows → Behaviour → Special key to move and resize windows → Disabled
After this change, Alt + Right Click Drag should work in Lumi for tool resizing.
Move around the canvas
Pan and zoom leave the current tool selected.
| Action | Shortcut |
|---|---|
| Pan | Middle Click & Drag |
| Pan | Hold Space and drag |
| Zoom | Ctrl + Middle Click & Drag |
Space pans by default.
Rotate the View
Turn the canvas so a practiced stroke runs in a comfortable direction. Painters and inkers do this often. Only the view turns. The image is not changed.
| Action | Shortcut |
|---|---|
| Rotate without leaving the current tool | Hold R and drag |
| Rotate the view | Shift + Middle Click & Drag |
| Rotate the view | Ctrl + Right Click & Drag |
| Snap that drag to 15° | Shift + Ctrl while dragging |
| Keep Rotate View selected | Click Rotate View, then drag. Shift snaps to 15°. Esc or Reset View returns to 0° |
Plain R cannot be remapped under Edit → Keyboard Shortcuts. Shift + R is Rectangle Select.
Configuration
To view or remap your existing bindings, navigate to:
Edit → Keyboard Shortcuts
A shortcut change is written as soon as you set it, while Save keyboard shortcuts on exit is on. That option is on by default.
