As it is I had to relearn my keys cus I was running out of room so I had to program my mouse (got this with my new computer WAY after farming WoD to give an idea) to using a side button to act as CTRL so I have an easier time. Right now I have 1-5, Shift 1-5, Ctrl 1-5 and pretty much every key around WASD set up to be used for a skill and I still have a couple more skills to add sitting at level 56 now.
