Does keyboard maestro have a trace/verbose log? I was experimenting with the "Highlight Location" action of Keyboard Maestro  yesterday. It worked.
Today it's not working.
How can I troubleshoot keyboard maestro?
When I press the play button on a macro, and nothing happens, is there an internal log I can inspect maybe?
There is a Keyboard Maestro debugger. Look under start for start debugging. You can single step through your script.
