1)	Add in generalised form of GOLD . to ask for the name of the mark to use. Default
	should be MAIN_MARK. This will also work between buffers.
	Use same mechanism as EVE (in SYS$EXAMPLES:EVE$EDIT.TPU).
	Save the MARK names in an array.
	Done (Dec-88) as F18. Called the EVE routines to do it so that it is exactly the
	save as EVE (actually, its trivial).

2)	Add in better mouse support.
	Done (Jan-89). Under VMS V5.1 mouse support is now greatly enhanced under DECwindows.
