# Voxtype Toggle Mode Switcher for Omarchy
#
# Switches Omarchy's Voxtype dictation from the default push-to-talk
# (hold to dictate, release to stop) to toggle mode (press once to start,
# press again to stop).
#
# This is useful if you prefer not to hold a key while dictating, especially
# for longer dictation sessions.
#
# Changes the keybind from:
#   Super+Ctrl+X (press)   → Start dictation
#   Super+Ctrl+X (release) → Stop dictation
# To:
#   Super+Ctrl+X → Toggle dictation on/off
