Aside from installing a Clipboard manager, open Windows Notepad and paste. Then copy from there and paste into RoboHelp.
Otherwise known as "the side trip".
Sad to see Rick's memory failing so early.
Rick introduced me to Pure Text. You copy to the clipboard in the normal way and then instead of using CTRL V you use Windows V (or whatever you set up in Pure Text) to paste in without any formatting.
No good for tables or images of course. It is, after all, Pure Text.

LOL, that's what I meant when I said "Aside from installing a Clipboard manager,..."
You would find it scary inside my "memory". LMAO!!!!
