Hi "kleveck220", and welcome t the User2User community!
No, sorry. Of course, if the recording is for a new project,
the END key will do fine. But you are obviously talking about
adding more slides to an existing project, and so far as I know,
the "camera" shots become a part of the project.
EDIT:
Have you tried the ESC key? I haven't, and don't know if that
would work or not, but you might try it and let us know what you
found ...
TIP
Before adding extra slides by reopening the Recording window,
determine where you want to add them, and insert two "Blank" slides
... so the new slides are added between them. Begin your recording
after the fist "blank" ... that way, if you don't like what you
recorded, you can easily "select" the newly added slides for a
multi-slide delete action.
Because of the nature of your question, I can't help but ask
how often this happens to you. Do you do a whole bunch of adding
slides during the Editing stage? You might be best served by
planning your project in more detail, and have a written "script"
in hand before doing the original recording. That would minimize
having to add slides later, I would think.
Hope this helps!
