Top priority would be the mouse.  We need to get cut&paste working.
(Including extend beyond the visible screen.  I believe I'm sending
the correct mouse events for that, but I haven't tested it.)

Find a tool to convert the reference doc to html, and just point a
browser at it for the help screen.  Have "novice", "fast lookup"
and an "everything" version.

Disassociate scrollbar actions from the cursor, i.e. when you
scroll the screen moves but the cursor doesn't.

Implement a "word search" button for the search dialog -- it's not
trivial, the ex/ex_subst.c/re_compile() routine is going to have to
allocate memory for the pattern which isn't going to make it happy.

/* TODO List:
 *	scrollbars	Need protocol messages that tell us what to display
 *			in the scrollbars.  Suggestion:
 *				scrollbar( bottom, lines, home )
 *				bottom is $
 *				lines is lines shown in the window
 *					(takes wrap into account)
 *				home is the line number ot the top visible line
 *
 *			On the way back send scroll( top )
 *
 *			User should be able to enable/disable bar display
 *
 *			<yuch!> horizontal scrollbar
 *
 *	expose_func
 *	insert/delete	When we have a partially obscured window, we only
 *			refresh a single line after scrolling.  I believe this
 *			is due to the exposure events all showing up after
 *			the scrolling is completed (pipe_input_func does all
 *			of the scrolling and then we get back to XtMainLoop)
 *
 *	split		Ought to be able to put a title on each pane
 *			Need protocol messages to shift focus
 *
 *	bell		user settable visible bell
 *
 *	busy		don't understand the protocol
 *
 *	mouse		need to send IPO_MOVE_CARET( row, column )
 *			(note that screen code does not know about tabs or
 *			line wraps)
 *			Connect to window manager cut buffer
 *			need to send IPO_EXTEND_SELECT( r1, c1, r2, c1 )
 *			otherwise core and screen duplicate selection logic
 *			Need to determine correct screen for event.  Not
 *			needed until split is implemented.
 *
 *	arrow keys	need to define a protocol.  I can easily send
 *			the vt100 sequences (and currently do).
 *			In general, we need to define what special keys
 *			do (for example PageUp) and what happens when we
 *			are in Insert mode.
 *
 *			Suggestion: IPO_COMMAND( string ).  vi core can
 *			take it as a command even when in insert mode.
 *
 *	icon		Is currently B&W.  To get a color icon, would
 *			require a lot of work or that bostic pick up
 *			the xpm library.
