I'm going to try to write a series of tips describing the new features of Keyboard Maestro 8. You can mute the "whatsnew" tag in your forum preferences if you're not interested.
There are a couple relatively common cases where things are unexpectedly happening or not happening, and the new Assistance window is largely designed to resolve two issues:
- Something unexpected is happening.
- Something expected is not happening.
You can open the window by selecting Assistance from the Help menu, and then you can choose from either of those options.
The Something unexpected is happening will show you how to ensure it is Keyboard Maestro Engine that is related to the problem, and also show you any macros that are triggered which will likely show you what is causing the unexpected behaviour, since it is very rare that Keyboard Maestro causes any unexpected behaviour except as part of a macro execution.
The Something expected is not happening will help you resolve the common "my macro is doing nothing" issue. It will do a health check on the system and engine, and assuming everything is ok, will let you select a macro and explain whether it is active or if not, why not and tell you when it fires (which would then indicate the issue is with the actions not working).
Of course, the usual problem with this sort of thing is that when people originally make this sort of issue they don't think to look for this sort of assistance, but it's there if you remember, and it gives me an easy thing to point to for these sorts of support problems (and I've had several people successfully use it already).
