Recently I've been trying to transition from an earlier version of Blender to 2.82. The UI is easy enough to figure out but the thing that really gets me is the bind to deselect all. In earlier versions, I could press A to select and deselect all but now I have to press Alt+A to deselect which really bothers me. If possible, I would like this to work in both Object and Edit mode.
I've tried going into preferences and changing the (de)select binds from Alt+A to A but it hasn't worked.
In essence, I want the keymapping to be the same as in earlier versions of blender; A to select and deselect all.
