On many keyboards today, they all have a shortcut key for the right-click menu.
This doesn't automatically fire the Right-click menu option (although most people think it should)
The keycode is 93. So if you want to support it, just put the following into the KeyDown or Keypress method:
IF keycode = 93
Be warned though - you can't use the traditional MROW() and MCOL() because the mouse cursor may not be where the focus really is. You may want to try passing a secondary parameter to identify the true starting row and column.
IF NOT tlKey
DEFINE POPUP SHORTCUT SHORTCUT FROM MROW(), MCOL()
** Figure out where you are
newx = ROW()
newy = COL()
DEFINE POPUP SHORTCUT SHORTCUT FROM newx,newy
