Perhaps you always know the tip.... but I just discover it last week 😒 

In the last version we change the icons display when you have a list of command (small symbol in the bottom right) and it is difficult to select it with the  ‘left key” of the mousse (like I always did it !) 😒 

But there is a more simple way to do => click on the icons with the right key (open the list) and click with the left to select the command 😀
