My hotkeys all go to "Layers", please help

I’m trying to get my feet wet here and I can’t even follow the getting started videos on the blender website. My left side menu doesn’t have the tool shelf heading or the add too thing and if I press “a” to try to select all it just changes the layer, and then almost any other button I press will continue to change the layer. Except for “c” or “v”, those make all the other keys stop doing it until I hit “a” again. I know I’ve got something screwed up here but no idea what it is.

Blender version?
Operating system?
Python installed?
Tried deleting configs or restoring default settings?
Reinstalled?
