Shortcuts 2.5

Hi guys,

As some of you might know, I only recently switched from C4D to Blender.
I’m currently in the process of editing the shortcuts to match C4Ds. Anyway, the problem is that C4D allows you to make a sequence of keys as shortcuts. For example U followed by Y will give me a grow selection. This gives me a much wider range instead of using only CTRL or Shift keys in sequence with other keys. It’s also much easier on the fingers.

I don’t seem to be able to do that in 2.5, does anybody have a workaround or a way to solve this? Or should I just bite the bullet and learn them all over again?
