After having installed Linux Mint 19.3 on an old MacBook Pro, I wanted to disable the Menu pop-up function on the ‘Left Command’ key press.
Delete the following entry in the Settings Editor(in the settings menu):
/commands/custom/Super_L | xfce4-popup-wiskermenu
First I could not delete the command. Then I simply deleted its value content:
Then I could click on the
Super_L and click on the
Reset button at the bottom.
The entry disappeared and the menu didn’t come up any more at the press of the
Left Command key.
