Run Chrome with a different user than the one who started Katalon

No.

Possibly, AutoHotKey,

Russ once said he uses AutoHotKey a lot

I don’t know AutoHotKey at all.


Do you want to execute AutoHotKey as a part of Katalon Test Case?

Once I posted a Test Case example which executes Windows dir command.

You can execute any commands by this method. Possible you can execute AutoHotKey script as well.
