But this is not the same :) I like follow the references when I thinking, but this feature disturb me.
Think about it: if a big tooltip will appear with zero delay in the source window, it would be also annoying despite you can move the mouse to empty area.
Alternatively a changeable tooltip delay time also would be fine
If you hate putting too many options to options dialog, a registry setting also acceptable for me.
VAX is very "handy" and customizeable, please keep up the good work
