Hi guys, not sure what's up, but I'm suddenly unable to perform a basic file rename in the Finder. I get a cocoa error notification (that's cut off in the notification window, so I can't even read the whole thing).
Oh, but handy tip, @Jack_Brannen: if you hover the mouse over the bottom edge of a macOS notification that has overflowing text content, you can drag it downwards to resize the frame of the notification until all of the text is visible.
When I have looked before, there was no way for Keyboard Maestro to use Notifications more constructively, but it is possible this very limited use might be possible.
