Peter please delete this if feel like it (of course you can do whatever you want since it is your forum) because I don’t want to intrude. Looks like Peter already answered your question directly so you should be covered.
I have tried several clipboard managers QuicKeys, QuickSilver, Launcbar, Clipboard History, Clipboard Center etc. Just found “Paste – Clipboard history manager” https://itunes.apple.com/us/app/paste-clipboard-history-manager/id967805235?mt=12&ign-mpt=uo%3D6 this week and I really like it in conjunction with use of a trackpad for two finger scrolling (though arrow keys work too). It’s different than any of the others that I have used in a good way. It was $2 on Tuesday so I have not time tested it.
My question to Peter is would you suggest not using applications like this in conjunction with Keyboard Maestro if you are not using Keyboard Maestro clipboard history. I worry about things conflicting like the documentation you posted states.
I think you pretty much already answered my question with this statement.
Can we have a single paste operation from the switchers that concatenates all selections together? Or, is it possible for me to write a macro that can read the selections in the switcher ? If I’m selecting multiple items to paste somewhere, I would rather that be one undo away from the previous state anyway.
There should not be any issues using multiple clipboard history apps together. Each one will read the clipboard. Some apps don’t like some of their clipboard flavors being read (Microsoft and Adobe apps are, unsurprisingly, the most common offenders), and having multiple apps reading the clipboard may increase the chances of those sorts of issues.
Keep in mind that each will have its own history, so if you delete an entry from one, it wont delete from the other. And things like how they deal with passwords may be different.
Its a good idea, I’ll add it to the list. The first half is on the list, but its always problematic in that you likely want some sort of separator, and then how do you set that? But the second one would allow you to build what you want, so it definitely has potential.
