Command and + key command

Here’s a quote from an SOS article: http://www.soundonsound.com/sos/jan12/articles/cubase-0112.htm

… the Command (Mac) or Ctrl (PC) key and plus (’+’) key combination, and Command/Cntrl key and minus (’-’) key combinations move the cursor forwards and backwards along the timeline in increments controlled by the Snap setting. So if Snap is set to a bar or beat, each press of the key command moves the cursor by that amount.

That doesn’t work for me no matter what snap settings I choose.

Could it be a CB8 bug under Yosemite? Does that works as described with CB7.5 under Mountain Lion?
