1) Since I have no modifier keys left on my laptop, and I'm an Emacs user (which takes away many C- and M- keybindings), I'd like to bind most XMonad actions with "C-z" as a prefix (using EZConfig).

Is there a way to bind a key so that "C-z C-z" sends a C-z to the currently focused window? (Ratpoison has a similar feature for C-t)

I did some googling and found out that: 1) the quickest solution is to use "xdotool" [http://www.semicomplete.com/projects/xdotool/], which can (among other nifty things), send a fake keypress to the currently focused window:: ("C-z C-z", spawn "xdotool key ctrl+z") 2) According to: http://www.handhelds.org/moin/moin.cgi/GeneratingSyntheticX11Events there are two Xlib programmatic solution, one using the XTest extension (recommended), and one using XSendEvent(). As far as I understand, there are no bindings for XTest in the Graphics.X11 module, so one has to code using sendEvent... With the following code, I have been able to send a Ctrl+Z to urxvt and "xev" windows directly from XMonad:: -- send Ctrl+Z to focused window sendCtrlZ = sendKey controlMask xK_z sendKey modmask keysym = withDisplay $ \d -> do keycode <- io $ keysymToKeycode d keysym root <- asks theRoot let subw = none -- FIXME: should this be the subwindow which the pointer is in? withFocused $ \w -> do io $ allocaXEvent $ \ev -> do setEventType ev keyPress setKeyEvent ev w root subw modmask keycode True sendEvent d w False noEventMask ev io $ allocaXEvent $ \ev -> do setEventType ev keyRelease setKeyEvent ev w root subw modmask keycode True sendEvent d w False noEventMask ev return () Thanks to all those who replied with suggestions to my original post!
