As we all know, while out of battles, the 6-slot bar located at the bottom left corner could be used with a key-bind to perform quick use/ equip. Example is to be able to quick use mounts, berries, etc. While the bar is still present on a battle screen, you can actually not use any key-binds to quick-action such items on the bar.
Although I understand that the bar indicating from 1-6 will conflict with the actual action bar (Attack, Pokemon, Items, Run.) I think it would be nice if we are able to bind these bars to another key-bind.
I am aware that it can simply be clicked, but I think having such mechanics would be nice. I think it would also be helpful to those who plays with a keyboard only and no mouse!
