Hey @John,
By the way – welcome to the forum.
FYI – in case you didn't know – you can type-select in the Groups and Macros panels to more quickly get to the group/macro you want.
Automating the Keyboard Maestro Editor
See specifically the Move Focus to Group List AppleScript.
Paste it into an Execute an AppleScript action in a macro, give the macro a keyboard shortcut, and you're one keystroke from being able to move the focus in the Keyboard Maestro Editor to the group list and type-selecting the group you want to get to.
There's also @DanThomas' great macro:
Go To Group by Name (Spotlight)
And there are other ways to do this as well.
Your English is not bad at all, but like @cfriend I wasn't able to fully follow your explanation in post #5.
Keep in mind that you can post images on the Forum, and sometimes a picture (real or mock-up) is worth a thousand words.
Sometimes posting a video on YouTube is required to get the point across.
A quick and dirty example of my own:
Keyboard Maestro - Setting a Safari Pop Up Menu
