1) Enter Preferences > Mapping > Global mapping 
2) Choose the action "Open Remote Buddy menu at main menu level" for 
the menu button, replacing the default "Open Remote Buddy menu" action

Disabling direct access to context menus and rather activating the 
respective Behaviour right away:

1) Enter Preferences > Menu 
2) Create a custom profile with a click on the plus button in the 
lower left or choose your existing custom profile 
3) Remove all Behaviour item from your menu layout and replace them 
with the respective actions found in Actions > Behaviours (in the Item 
Library on the left)

Best regards, 
Felix
