AHK is a pretty Windows ecosystem-specific crutch and everything it does is done in different ways in other systems. TC can be run on Wine absolutely everywhere, I used to do this on Linux for a number of years and it's perfect including plugins, although there are plenty of good FMs out there (e.g. DoubleCommander is a near-direct replacement) so feel free to try them if you just need a way to manage your files and not your specific setup in particular. Log in as Administrator... uh what? Not sure what you mean. Not requiring admin password on system-wide actions? Sure, it's trivial everywhere.

Double Commander is pretty good: https://doublecmd.sourceforge.io/

It's cross-platform, so could switch file manager on Windows first to make it easier to switch to Linux later.

If you need Autohotkey you can still run that under wine (if you are ahk on windows applications), you can run total commander under wine. You can log in as admin I think its time to make the switch

Oh, I also need a way to compile CodeBrowser 4.9 [1]
