- This uses global pref keys (hardcoded) because the preference is supposed
to remain in all commands. Other option is to ask the command or parentWidget
for the prefs_key. If we want to support local prefs keys (e.g. turn on the labels
while in certain commands only, then perhaps it should ask for prefs keys from
the command. (and there needs an API method in command so that its implemented for all
command classes. The latter seems unncecessary at this time,
