The XKB X server extension allows to bind mouse events to the
keyboard. Q 3.5 in our FAQ has a short description of that
feature:

----------------------------------------------------------------------

3.5 You can bind mouse movements to keystrokes, how about mouse
     presses?

A: Although fvwm has commands for binding movements to keystrokes,
   controlling the pointer with the keyboard should really be handled by
   the X server. The following is an excerpt of the X FAQ on this topic:


      If you have the X Keyboard (XKB) Extension, you can enable mouse keys,
      which makes it possible to generate mouse motion and button events
      using the keyboard. Events generated by MouseKeys are completely
      transparent -- they will work with any application that connects to a
      server that has the X Keyboard Extension, regardless of whether the
      application itself uses XKB.

      XKB is enabled by default in X11R6.1.

      First, set up the Num Lock key so that Shift+Num_Lock toggles mouse keys:

       xmodmap -e "keysym Num_Lock = Num_Lock Pointer_EnableKeys"

      (XFree86 3.1.2E is based on R6.1 and has the X Keyboard Extension;
      it also has a binding to Pointer_EnableKeys in its default keymap.
      You use Alt+Shift+Num_Lock to toggle MouseKeys on and off. If you
      are using an earlier release of X or XFree86, you won't have XKB and
      the instructions will not work. See http://www.XFree86.org/FAQ for
      more information.)

      You might also have to turn off server num lock for this to work.
      Now press "Shift+Num_Lock" to enable MouseKeys. When MouseKeys are on:

      o) The keypad arrow keys move the pointer
      o) The keypad '5' key behaves like the 'default' pointer button
      o) The keypad '0' key locks the default pointer button (for easy
           dragging)
      o) The keypad '.' key unlock the default pointer button (to release
           a drag)
      o) The keypad '+' key double-clicks the default pointer button.
      o) The keypad '/' key sets the 'default' button to Button1
      o) The keypad '*' key sets the default button to Button2
      o) The keypad '-' key sets the default button to Button3

      This is the default configuration, but the mechanism allows for nearly
      infinite configurability.

----------------------------------------------------------------------

Personally, I have this in my $HOME/.Xmodmap:

  keycode 0x73 = Pointer_Button3 Pointer_Drag3 Super_L
  keycode 0x74 = Pointer_Button2 Pointer_Drag2 Super_R
  keycode 0x75 = Pointer_Button1 Pointer_Drag1 Pointer_EnableKeys

This binds button 1 to the "menu" key on my keyboard (one of those
pesky Micro$oft keys), Button 2 to the left windoze key and
button 3 to the right one. Dragging with a button is a bit more
complicated. You have to press Shift-<key> to start dragging,
then Shift-<key> again to stop dragging.

What is really annoying about this feature is that the button
emulation times out every few minutes and you have to enable it
again by pressing RightAlt-menukey. To enable it permanently, you
need some external program, but I do not remember how it is
called.
