That's a good point. At current I don't know that any actions in my daily apps are mapped to that combination, but if it does come up, I've written a note to my self to sequester this macro in it's own group. I think having one macro group containing one macro is still better than having 5+ macros in their respective app-specific macro groups.
@JMichaelTX , I was confused at first about how exactly I would use a Switch to check for app, but then I read your ACTION: Switch Case Based on FrontMost App that taught me about the %Application%1% token. I confess I didn't know about those!
I think I'm going to use a block of If/Then/Else for the web-based editors and a block for apps using a switch. Mainly I'm keeping it mixed so I'll remember what you can do with switches and tokens.
Thanks for the help and friendly debate
