Hi All,

I have a small problem with handling control messages for my view. The view
displays a graph which contains 'figures' (points on the graphs, axis
labels etc)which are managed via clicking and dragging; and interpreting
keyboard input eg tabs. What I would like to do is have the view interpret
keyboard and mouse together (not using the modifiers): say, down arrow and
mouse click, to draw a figure on the graph differently from an up arrow and
mouseclick. (Arrow determines type to draw and mouse click determines
where.)

PROCEDURE (v: View) HandleCtrlMsg*
   WITH msg: Controllers.PollOpsMsg DO
    
   | msg: Controllers.TrackMsg DO (for mouse action)
   (I'm using a mouse tracking loop similar to the Buttons example...)

   | msg: Controllers.EditMsg DO (for keyboard action)

   I can't seem to interpret two messages together?

Many Thanks
Mary Kynn
