 Arrow labels can auto-number when enabled in the arrow toolbar; reset with <kbd>Ctrl+Shift+R</kbd>. Step markers auto-increment and reset from the toolbar (or bind `reset_step_markers` in `config.toml`). Preset slots can be saved/cleared from the toolbar; edit names and advanced fields in `config.toml`. Blur has no default keyboard shortcut; bind `select_blur_tool` in `config.toml` if you want direct keyboard access.

 ### Light Passthrough Mode
 
-Light mode hides UI chrome and sets the overlay to click-through passthrough until drawing is explicitly enabled. `toggle_light_mode` defaults to <kbd>Ctrl+Shift+L</kbd>, but that is a Wayscriber in-overlay shortcut: it works while the overlay still has focus. Once passthrough is active, normal keyboard and pointer input goes to the app underneath, so compositor/global shortcuts should call the daemon commands below for reliable control.

 This mode requires compositor overlay support through layer-shell. It is disabled on the xdg fallback because regular app windows cannot reliably stay visible as click-through shell overlays while keyboard and pointer input go to apps underneath. On stock GNOME Wayland, Freeze may still work for still-image capture when portal capture is available, but it is not a live passthrough replacement. True passthrough would require a GNOME Shell extension companion.
