Some custom utilities (e.g., KMonad, Karabiner-Elements) allow requiring a 200ms hold on the modifier before switching, preventing brief accidental presses. To reduce errors and improve efficiency, users and
For power users, the shortcut can be disabled entirely for certain apps (e.g., coding IDEs) where accidental layout changes break syntax input.
