Good suggestions. I've done so. I also did a copy-replace of 'paste' for 'send', to assist people in searching. I suspect many more people will think 'paste' than 'send', even if the low-level X functions are named in terms of the latter.

Ah. I feel a little guilty bypassing the Mod* types to plug in in a 0, but it works, it seems.

Maybe. It's not really an issue for this code, is it? Since the type only takes Char, one cannot make it run stringToKeysym on a invalid string like "foo". And the functions lower down are in terms of Keysyms. (Although I wonder if perhaps that bit of functionality should be explored in the X11 haddocks. I didn't notice anything in particular.)


Well, anyway. I've sent in a module if people want to look at it.
