Hi, I am very new to Linux and very much windows savvy. I found Linux a bit difficult but when I use centos I am very much interested in Linux. Just want some basic information. There are work spaces in Linux, I can switch them by using mouse but is there any keyboard shortcut to switch in between then?
I use Ctrl +Alt + arrow keys but it is not working. I check those settings in System --> Preferences -- Keyboard and Keyboard Shortcuts. Those are set correctly, but only Ctrl + Alt + Up and Ctrl + Alt + Down works properly. Ctrl + Alt + Left and Ctrl + Alt + Right are not working properly when I tried to switch to left and right workspace respectively. Is it any kind of bug?

Pls help!!!

Thanks in advance!!!
