DOpus has the command Select RESELECT. Docs:
Reselects all files and folders that were used (and deselected) by the previously executed command.
There's the older thread "Is there a way to undo a deselect?", in which Leo said:
the more I think that through the trickier it is to define a good rule for which selection events can be undone, and which events overwrite the saved selection you'd go back to, which could become quite a fragile piece of state, such as if one file was selected and then another.
How about letting the script writer store the selection explicitly, though? I had a use case where I wanted to do this in the context of showing the folder context menu, but had to accept the selection as cleared after calling Select NONE, because I found no way to restore it.
If a selection-storing companion command to Select RESELECT would exist, I'd call it in my use case, then Select NONE, then let Talon simulate the menu key, and finally call Select RESELECT.
I don't know, however, if this tampers too much with the reasons Select RESELECT was made available in the first place, so that technical use cases like mine and more user-involved command execution would be mixed inappropriately. If that distinction is reasonable, a technical use case could leave traces of state in the user-involved realm by overwriting the last selection undo information. But that's just a cautious thought and could well be irrelavant.
