Am sorry But I use Fedora and surely someone using Fedora might know an answer to my question.G'day @Chiff and welcome to linux.org
First, just a small lesson on forum protocol and etiquette which applies not only here, but around other forums as well.
You have this here at Fedora
We can't be expected to be mindreaders (my crystal ball is in at the shop for service), nor their helpers - in knowing what has been asked and input elsewhere.
Please don't do it - close one or the other if you feel you are not getting helped.
On your subject matter, what DE (desktop environment) are you using - GNOME, or one of the community flavours, and if so which?
Firstly, thank you for your kind help. I really appreciate it. Am only new to Linux.AFAIK Gnome uses a registry. It used to be called gconf. I think it's now called dconf.
From doing a quick bit of duckduckgo-fu - this thread on the askubuntu.com forum might help you a little. (I know you're running Fedora, but you're still running Gnome, so it should still be relevant!)
I usually load a new version for every release to keep my OS fresh while preserving the last version on another partition as backup. I also employ a lot of custom key mappings. I've figured out how...askubuntu.com
Personally, I don't use Gnome. I use dwm. So all of my custom keybinds are in a C header file. So if I make any changes to my keybinds, I have to re-compile and re-install dwm and then log out and back in again! Ha ha!
