Paste text copied from Excel into External App.using right mouse click
 

I have code to copy text to the clipboard from Excel. If I switch to
the external App and get field focus is there an API function that can
trigger a paste from the clipboard using the right mouse button? This
action would ideally release this API "reserved function" until the
user returns to excel and repeats a copy. This is to allow a disabled
user to copy (done this bit) and paste just using a mouse.
