# kconf update script to migrate users who previously disabled
# activateWhenTypingOnDesktop for KRunner. This script only flips
# users who explicitly set the key to "false" to "true" and
# leaves unset keys untouched.

# Minimal behavior:
# - Locate the user config file (prefer $HOME/.config/krunnerrc)
# - If the file exists and contains the key ActivateWhenTypingOnDesktop,
#   set that key to "true" (make a backup first). Do not create the key.
