Microsoft is now fixing one of the bigger headaches there: the Xbox Game Bar.
When using a controller, you could switch between widgets quickly with left and right bumpers (LB/RB).
However, most Windows handheld consoles (if not all) can map keyboard shortcuts to physical buttons.
Microsoft suggests mapping a button to the Win+G shortcut if you want easy access.
This is one of Microsofts first steps towards fixing that.
