[xmonad] Layout switching (rather than cycling)

Hi, How can I bind certain layouts to key combinations? So rather than cycle thorugh layouts with Mod Space, I'd like Mod F1 to give me layout 1, Mod F2 to give me layout 2, etc... I've been googling for a bit, but can't find an answer. Thanks. anze phone: +1 (510) 495 2488, mobile: +1 (510) 289 9395, fax: +1 (510) 486 7149 -- "Neprijavljen student na Praktikumu je namrec nezgresljiv znak za kosmatinca, ki je prisel k nam le prezimit."
