Realize that what you mean with "to get used to this new OS" is possibly "I need to get used to this desktop environment / window manager". I don't know what desktop environment you use but it is possibly Ubuntu's Unity, Gnome or KDE.
On Unix you have a lot of choice on the (graphical) interface you chose to interact with. So while to one you're currently using might be OK, there's bound to be one that's even better suited to your needs.
yep thanks. I run ParrotOS which is basically debian with some slick UI and pentesting toolsets. It is a gnome desktop enviro. I will check those links out. The keybindings did not hold on the tut I followed, no biggie. My major point is that I am a mac superuser, but when I switch windows I have to manually deselect a window (because it follows me). It is just absorbing the nuances of linux and inculcating the macros into my head.

(Also, it's usually trivial to change your keybindings.)
