Mouse / screen edge = hotkeys (as compiz replacement)?

Question

Hi!
I'm looking for something that lets me configure commands / keyboard shortcuts to be executed when I move my mouse to the screen edges / corners
P.E.: "top edge + mouse4 => [meta+x]; "top edge + mouse5" => [meta+y]; hover / touch top right corner: [alt+something]
(... because compiz lets me configure plugins like this but kde doesn't. And I need to replace compiz with something for a long while now because It's been falling apart more and more over the last few years. )

Thanks!
Regarding shell implementations: It's been a while, but I'll try to remember some of the problems I ran into and which made me come to the conclusion that a script isn't the right angle to tackle the problem:
- The poll intervall that is needed so button presses aren't missed is too low to be cpu friendly
- Mouse wheel is even worse. Needs some kind of buffer + limiter too, because otherwise something between the program that sends the keyboard events and the window manager or whatever it is that catches them might oveflow / freeze / something
- Leads to all kind of weird behaviour when applications try to grab raw input
- Goes totally nuts / needs to kill itself if an application sets mouse to that wrap around mode thing that I don't know how it's called or works...
- Various weird behaviour on resolution changes need to be considered depending on which shell tools are used and how
- Also there were lots of other small issues
- And the more problems I solved, the more cpu it needed until in the end it was absolutely unviable and I had to start over / quit
And regarding a potential xlib c (or is that c++?) implementation: I'll needs to look at that snippet for a few hours before I can tell for sure, but on a first glance I'm almost sure I'm falling about 2 years worth of regular C / graphical / whatever programming experience short of being able to work with xlib + raw input stuff or whatever that is and reading some xlib docs for a few hours probably won't put a dent in that. I briefly tried modifying "xev" to suit my needs about a year ago and that didn't go too well - gave up because I was fairly certain that by the time I'd be finished learning x + xlib stuff everyone'd be using wayland. (I'm NOT that sort of "programmer"; more of a "scripter" if at all. As a rule of thumb: if it's supposed to be run on a headless server, parses text, moves files or writes into a database, I might be able to modify it or even write it. If on the other hand it has "pointers" or "h-files", then as soon as I change the code in any way it will never ever compile again no matter for how long I google the error message. :3 )
So... I guess that means noone knows if there's a "hot-bar-panel" or anything that captures mouse input on the screen edge hiding somewhere in AUR or on github?
