+## Start with the laptop keyboard layout
+
+Run `cthulhu -l` to use the laptop layout with Caps Lock as the Cthulhu
+modifier for this session. No number pad is needed. The selection stays
+active when switching applications and does not change the saved profile.
+Starting without `-l` uses the saved keyboard settings again.
+
+Press Caps Lock+Space to open Preferences. Applying preferences replaces the
+temporary selection; save the laptop layout there to make it permanent.
+Use `cthulhu -l -s` to open Preferences at startup.
