[xmonad] Configuration question

[Evan Driscoll]

I have a question about how to configure things for a certain behavior.

A short version which suffices: is it possible to set up a keybinding to 
change the keybindings?

Here's what I'm actually trying to do:

I find that most of the time my workflow basically has me changing 
between two or three different "projects". (For instance, working on a 
couple different development projects with different source trees, etc.) 
Each project usually takes up a couple virtual desktops.

What I would like is something like a two-tiered virtual desktop setup, 
where I could have different project spaces each with its own set of 
virtual desktops. So for instance, Mod-F1 would change to project A, and 
Mod-1 through Mod-5 would choose between the desktops for project A. 
Then Mod-F2 would change to project B, and Mod-1 through Mod-5 would 
choose between the desktops for Project B.


I have a small amount of Haskell knowledge, but only a small amount. I'd 
appreciate any suggestions.
