Is it possible to copy/duplicate a Key Command Macro? (and then edit it from there)
I have some useful macro operations I’d like to do which are only slightly different from each other and it would be rather tedious to have to reconstruct the bulk of the macro again-and-again from scratch for each minor variant. Is that what I’m going to have to do?
No, unfortunately. Some people have messed around with the KeyCommands.xml file, if you’re into that sort of thing. If you understand how xml file syntax/format works you might be able to use it. I remember having trouble editing macros, but I was able to edit simple keystroke shortcuts.
