... is very cool. Time to ditch fvwm95 ;)

One of (IMHO) the must-have features of fvwm2/95 was the ability to move
windows to an arbitrary point on the screen using the keyboard; E didn't seem
to be able to do it, but I've hacked it up using eesh (which is really cool).
Details at the end of this mail.

But I have a question...

Does anyone know why I can't rebind the "windows start menu" key on my
keyboard?  Worked fine in fvwm, but E doesn't like it. It's supposedly rebound
to Mode_switch using xmodmap, and xev, xkeycaps, xmodmap etc. all suggest that
this is the case, but even though other keys bound to Mode_switch do what the
keybindings.cfg file says they should, this one won't.  Does E treat it as a
special key internally? Can't find anything in the source to suggest it...

I find this odd, though. xev reports the KeyRelease event with a state of 0x2000,
which seems to correspond to a ButtonMotionMask in X.h...

KeyPress event, serial 24, synthetic NO, window 0x4c00001,
    root 0x25, subw 0x0, time 1735037215, (108,103), root:(451,800),
    state 0x0, keycode 117 (keysym 0xff7e, Mode_switch), same_screen YES,
    XLookupString gives 0 characters:  ""
KeyRelease event, serial 24, synthetic NO, window 0x4c00001,
    root 0x25, subw 0x0, time 1735037293, (153,107), root:(496,804),
    state 0x2000, keycode 117 (keysym 0xff7e, Mode_switch), same_screen YES,
    XLookupString gives 0 characters:  ""



Anyway, if you're interested in the window-movement hack, here it is.
My keybindings.cfg now contains:

    __EVENT __MOUSE_PRESS
    __BUTTON 1
    __MODIFIER_KEY __CTRL_SHIFT
    __ACTION __A_EXEC "emovewindow . 2 2"

and 

    __EVENT __MOUSE_PRESS
    __BUTTON 3
    __MODIFIER_KEY __CTRL_SHIFT
    __ACTION __A_EXEC "emovewindow . 625 2"

where emovewindow is a script as follows:

  #!/bin/sh

  usage () {
    echo "usage: emovewindow window-id x y" 1>&2
    echo "x or y can be \".\", in which case they will stay the same." 1>&2
    echo "if window-id is \".\", the focused window will be moved." 1>&2
    exit 1
  }

  [ $# != 3 ] && usage
  window=$1
  x=$2
  y=$3

  if [ $window = . ] ; then
    set -- `eesh -ewait 'window_list' | head -1`
    window=$1
  fi

  if [ $x = . -o $y = . ] ; then
    set -- `eesh -ewait 'win_op '"$window"' move ? ?'`
    # window location: x y
    lastx=$3; lasty=$4
    [ $x = . ] && x=$lastx
    [ $y = . ] && y=$lasty
  fi

  exec eesh -e "win_op $window move $x $y"

Hey presto.
