I'm not sure the title is clear so I'll try to specify. I currently have Ubuntu 12.04 with Gnome installed on it. I've done at least 16 hours of random tweaking and reading, mostly to give myself a better user experience.
I've installed and modified Sublime Text 2, installed a bunch of drivers, software, transferred files, etc. I want to know if I install Cinnamon and use it instead of Gnome, will it change my settings? For example, I have a "Show Desktop" keybinding set up (Super + D) that took me a while to figure out how to get working, will Cinnamon make me re-modify it?
