Short cuts for split screens don´t work[FIXED]

Hi again,

i´ve just tried the split screen mode and tested the shortcuts like they are standing in the tutorial
(ctrg + =, ctrg + =´, and ctrg + shift + ") and obviously they don´t work. Maybe i just use the wrong shortcuts, but I don´t think so.

Greetings

FIX: Tutorial Updated

What version are you using? Two out of three (ctrl + =, ctrl + =´) work for me and by trial and error I found that ctrl + shift + ’ works for vertical split so I assume that ctrl + shift + " is an error in the tutorial.

-1.55 on Vista Home Premium.

EDIT: View -> Layout shows ctrl + shift + ’ as the short-cut for vertical shift, so there is an error in the tutorial.
