You might remember my previous post about what I wish to have in Gnome3.
I have just found out some from "gconf-editor".
To reach to Favourited Items;
After pressing "Start" button, you can press <Control><Alt>Tab combination to switch betwen Dash, Windows, Topbar etc.
Selecting "Dash" will take to your the list of your favourited items.
Just press <Control>Enter to start a new instance of the application.
Switch between multiple instances of same application;
You know when you press <Alt>Tab to switch between multiple appilcations.
If you have multiple instances of same application, reaching to Arrows key hinder your selections.
Just press <Alt>` (the one above the Tab) key to swtich.
Well...this isn't a big discovery, but if you have not known them, it might be of some help.
