Which letters have the most wear on your keyboard?

In My Humble Opinion
41

WASD

42

F5

43

A, S, E, the left Shift, and the Space Bar, as well as the left and down cursor keys, which I use for scrolling (I don’t use a mouse so don’t have a scroll button). I have, in fact, worn an actual hole in my down cursor key.

I’ve had this keyboard for 10 years, and it’s my favouritest ever, because it’s basic (without all the extraneous junk keys that plague peripherals), is NON-clicky, and has most keys just where I want them.
