Tool selection keys - Reverting to what they were

In previous versions of Sonar, the keys for changing tool were all clustered around WASD, which is convenient for those of us who are used to having our left hand over there.

X1 requires us to either use function keys or hold down a mouse button to change the tool.  I still haven't gotten used to it, and find this extremely annoying.

So, I'm thinking about reverting to the old keys.

I am curious how many of you have done the same thing. 

Do you miss the old tools?
