key-mapper VS XMousePasteBlock

This may help you!

Another option is key-mapper which runs as a systemd service and lets you map all kinds of things to other things.

Key-mapper

Being a previous windows user I have a mindset that I shouldn't download non mainstream or non trusted applications on my system especially the ones that have admin access or physical device access . I wanted to remap my keyboard in such way which allows me to use capslock key as backspace and alt_r key as escape. setxkbmap and Xmodmap isn't giving required results or I am not too advance to use it properly . I recently stumbled upon this program key-mapper but it requires admin access so should I trust it for daily use. ( I am not a developer and thus does not understand what any of the code does )

There's Key Mapper which I haven't tried yet (still on my 100% rubberdome at the moment so no need) but it looks very promising.

I've actually been using XMousePasteBlock since it does things more elegantly than running an endless loop in the background. But it's still a workaround that shouldn't be necessary unfortunately.

Also, don't run this incredibly bad bash script for purging the X11 selection buffer. Use XMousePasteBlock: https://github.com/milaq/XMousePasteBlock

This is what I use on X11, but I doubt it would work on Wayland. Might be worth trying anyway: https://github.com/milaq/XMousePasteBlock

here go: https://github.com/milaq/XMousePasteBlock

I'm pretty sure I used https://github.com/milaq/XMousePasteBlock, never had to deal with it since

The option to turn it off only works on GTK apps. Here you have a workaround for this. I've been using it for quite some time now and works great so far (I'm on Pop btw).

This tool named XMousePasteBlock may help you, and it has an AUR package if you use ArchLinux.
