Is There an Automated Method to Select the First Action Within a Group Action?

I've got an unpublished macro that I'll likely share in the Keyboard Maestro Editor Megathread, but my current implementation uses a fragile method to select the first action within a selected Group action.

Is there a way to do this with with AppleScript (or any other robust method)?

Something like this?

tell application "Keyboard Maestro"
   set theSelection to the selection
   if theSelection ≠ {} then
      set theSelection to item 1 of theSelection
      if class of theSelection is action then
         tell theSelection to set action1 to its first action
      end if
   end if
end tell

That'll throw an error if an "If", "Catch", or similar is selected rather than a "Group". It may not matter for @_jims's use-case, and the only way I can see to be reliably specific it's a "Group" action would be to test for all of thenactions, catchactions etc being missing values. Probably easier to handle the error in some way!

Yes, well – I answered the question that was asked...

This is not panacea for all possibilities, but it gives the general idea:

tell application "Keyboard Maestro"
   set theSelection to the selection
   if theSelection ≠ {} then
      set theSelection to item 1 of theSelection
      
      if (count of theSelection's thenactions's actions) > 0 then
         select theSelection's thenactions's actions's item 1
      else if (count of theSelection's elseactions's actions) > 0 then
         select theSelection's elseactions's actions's item 1
      else if (count of theSelection's tryactions's actions) > 0 then
         select theSelection's tryactions's actions's item 1
      else if (count of theSelection's catchactions's actions) > 0 then
         select theSelection's catchactions's actions's item 1
      end if
      
   end if
end tell

Thanks, @ccstone; you did the hard part. I had to just add one line to the AppleScript.

@ccstone and @Nige_S, thanks so much for your responses to my question. For my use-case, here's what I've come up with thanks to your expert help.
