Comment #3 on issue 182 by gwe...@gmail.com: Key bindings should be showable http://code.google.com/p/xmonad/issues/detail?id=182 I vote for #3. #1 and 2 both look like they will break extensions, configs, or both, and people simply don't care about newbie documentation enough to support breakage just for their sake. #3 avoids this, so actually has a chance of getting consensus. Simplest would just be binding M-? to xmessage with a large static string specifying the defaults. Zero breakage\* and the newbies get the documentation they need; people customizing their config already know what keys they modified. Technically, we'd have to update it every time we change the default bindings. As far as I can tell, the last time a binding was added or removed (rather than fixed or improved), was almost four years ago, in March 2008 when Spencer commented out M-b which was some sort of toolbar-gap-toggle. This seems like an improvement to me. \* anyone binding M-? in their existing config will be overriding the default keymap and so will not be affected. And as far as I can tell, no one *does* - in the XMonad config archive are only two hits for `xK_slash`, both of which are not shifted and so not question-mark bindings.
