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

ActionShortcut
Adjust Brush SizeAlt + Right Click & Drag
Cycle Select LayersAlt + Hover over canvas
ℹ️

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.

  1. Search the system menu for Windows.
  2. Windows → Behaviour → Special key to move and resize windows → Disabled

After this change, Alt + Right Click Drag should work in Lumi for tool resizing.

Configuration & Persistence

To view or remap your existing bindings, navigate to:

Edit → Keyboard Shortcuts

Note on Persistence: Your custom shortcut configuration is committed to your configuration file only upon a proper File → Quit. Please ensure you close the application via the menu after making significant changes to ensure your settings are persisted.
