Recommendation on PageUp PageDown key bind and the UI

I did notice that from the beta you simplified how those keys are displayed on the UI. I use the numkeypad a lot and the text was really long and it looked really bad on the bottom right corner of the screen with all the shortcuts. Now its just N1, N2, etc. looks clean. Awesome work.

BUT ... PageUp PageDown haven't been shortened. It goes over the guns fire mode in my case so it's really hard to see if I'm in auto, single, etc. Should be an easy fix. Please change it to something like PU or PD or PUP PDN so it doesn't go over other UI elements.
