Further playing with the automation lexer wasn't very fruitful...
Having a brief look into the ahk tutorial shows, there is a feature to label hotkey functions and setting options: https://www.autohotkey.com/docs/Hotstrings.htm

I tried to get detect the labels correctly for the following snippet.

#p::
Run, https://www.pygments.org/
return

^t::
Run, calc.exe
return

:*:pyg::pyg
::pygmentize::pygmentize

This snippet results in differing tokens as well. :*:pyg:: and ::pygmentize:: are so called hotstrings (labels for a hotkey sequence), but one receives the plain Name token and the other Name.Label.

Anyhow, I am unable to find a quick solution. Rethinking this lexer would require some time... I'd drop the respective commit stashing it for later. Maybe I have a better understanding on pygments' code then - or someone else will address this...

Sounds like a plan. I'd rather have this noted as an open issue than introduce this kind of change during a cleanup -- thanks for investigating this!

Merged, thanks a lot!
