Keymap Set Lite is an add-on that provides alternative input configurations for viewport navigation and transform operations. It enables Q, W, E, and R hotkeys for transform gizmos, alongside Alt-based viewport navigation using mouse button inputs.

Users can toggle these specific keymaps via checkboxes without needing to edit or load standard key configuration files. To accommodate the new layout, the add-on automatically assigns alternative keys for conflicting default shortcuts, adapting Extrude to Ctrl+E and Loop Select to Alt-Double Click.
