[Xmonad] Re: reserved keyboard shortcuts

after an update from darcs, i see alt-LeftArrow and alt-RightArrow are no longer used as shortcuts, which is nice because they are used in firefox. alt-b is still in the default, which is used to access the firefox bookmarks menu.

i personally maintain a private Config.hs to deal with this, not sure if it is something worth addressing

Is it possible to allow defining keys combination as the modifier? I used to be a wmii user, on which I define Ctrl-t as the modifier a la Ratpoison and Emacs. Thanks
