Problem with opening menu via hardware key on Galaxy A320F

[MVV]

On my old phone (Lenovo A1000) I could hold Recent apps button for main menu so I've disabled menu bar which takes too much screen space.
However I've found that on my new phone (Samsung Galaxy A320F) I have to hold Back key for main menu, and TC goes back multiple times until menu appears, so it is not usable.
Is there a way to hold another hardware key for opening main menu?

No, unfortunately not. But you can add a button with command 500 to the lower button bar to open the main menu.
