There is, but it's a fair amount of work. Right-clicking displays a context
menu -- which one depends on what's selected at the time. And there are LOTS
of possibilities, thus LOTS of menus to which you'll have to add it.
Right-click a toolbar and select Customize. On the Toolsbars tab, select
'Shortcut Menus'. This displays a toolbar that gives you access to all the
context menus for purposes of customizing. Add EditPasteSpecial to each one
that yuou use.
