Macros in 2007 - Paste Unformatted Text

[Colin]

In Word and Excel 2007, I can record a Macro and then edit it in the VBA
editor. I can then assign it a shortcut. I don't seem to be able to do this
in PowerPoint 2007. Am I missing something, or is this a limitation of
PowerPoint compared with those other Office programs?

If so, maybe there's another way to do this:

All I want is to make a quick keyboard shortcut for Paste Unformatted Text.
In Word and Excel, I've assigned this to Ctrl-Shift-V. Is there any way to
make a similar shortcut in PowerPoint (with or without using macros or VBA)?

Thanks,
Colin
