I’ve switched to use DWM, Dynamic Windows Manager, from GNOME on my laptop since the beginning of this month. So far I really enjoyed it.

Here are some commands I needed to know since I have an external screen connected ot this machine.

To change the focus to previous/next screen:

Mod1 + ,
Mod1 + .

To move applications from a screen to another, just add Shift key:

Mod1 + Shift + ,
Mod1 + Shift + .
