1. You need to file a package request.
2. What can this do that xcape, which we already have, can't?

I did not understand very much .

I'm sorry , I don't speak english very well ,I use Google translate.

It is not optional I'm using an instant translation program that needs xbindkeys,xsel .

I've packaged xsel,xbindkeys,st-trans .

I'm no longer interested , I have already installed them.

I am a Fedora user and I tried solus, and I found an excellent distribution, but the number of packets is small, but it is one of the best distributions I have tried in several years.

Again sorry for my English

Good Luck.

Thank you.
