Map ex Commands in vim

In vim, Greek, and utf-8 Keyboard Commands, Giorgos had asked in a comment if it would be possible to not only switch vi's keyboard shortcuts to a Greek keyboard, but also to use Greek letters for ex commands. For example to be able to write :γ for :w. Yes, that's possible, do something like the following in your .vimrc file:

cab γ w
cab κ q
cab γκ wq
cab ε e

Due to the use of cab for these "abbreviations" (that's what the ab is for), they will work only in the command mode. There are some limitations. First of all, when entering :γ you will not see it replace with :w right away (you can hit space to see it replaced), but it will work. Also if you have ex command lines with a single ε somewhere in them for example, you could get into trouble, as vim would continue to change that to an "e". I will not be using this myself for this reason.
