"Moded" Keys in FVWM

I am highly encouraged to use the FVWM2 X Window Manager at work on Linux.
Not exactly forced, but other options are a hassle.

Finally got around to providing some key bindings.

In particular, this hack to enter a "mode" where a window's size is changed by repeated key presses
(1) define a menu with hotkeys calling a function
(2) have the function perform the action (e.g. narrowing the window), and then re-invoke the menu with the hotkeys.

I haven't seen it described in the FVWM2 FAQ, although I got the idea from a FAQ suggestion wrt using hotkeys.

# From the fvwm2 FAQ
#7.9  Moving the mouse/focus/page with the keyboard.
#
#   Try these key bindings for mouse movement:
#
#     # shift- to move a few pixels
#     Key   Left   A   S   CursorMove -1 0
#     Key   Right  A   S   CursorMove +1 +0
#     Key   Up     A   S   CursorMove +0 -1
#     Key   Down   A   S   CursorMove +0 +1

# Glew version of these bindings

# - I wish I had a modifier reserved for the X/VNC/FVMW2 window manager
# but since I am running Emacs meta is usually taken
# and since I am running under VNC on Windows the Windows key is taken
# (Moral: needone key per layer of Window Manager)

# so, anyway, the closest thing I have to a free modifier is meta-arrow

# shift- to move a few pixels
Key   Left   A   M   CursorMove -1 0
Key   Right  A   M   CursorMove +1 +0
Key   Up     A   M   CursorMove +0 -1
Key   Down   A   M   CursorMove +0 +1
