Could it be that there are no keyboard shortcuts to change Multidock Tabs? Or I am looking in the wrong place?

Ctrl+Shift then left or right arrow.

I maybe so in for Craig , 
I can't find these bindings in online list http://www.cakewalk.com/D...age=3&help=0x18323
I just set my bindings to SONAR Default Key Assignments and Ctrl+Shift then left or right arrow both state... Assigned to: [Unassigned]
Best way is to set them yourself... Preferences / Keyboard shortcuts / and under the search tab write “Tab”
you should have 3 listed, previous, next and close current
hth

When checking shortcut assignments in Preferences make sure to have a project loaded. When I check CTRL+SHIFT+Left and CTRL+SHIFT+Right with a project open, the Global Bindings area shows Previous Tab and Next Tab respectively.

WOW! "me too" learnt something new, this is something I'll have to watch in future
but I don't understand why having a project open would make bindings appear.
 
Suppose I'll have to add it to the list other things I don't understand, like, "dark energy" and why I have short term memory loss after drinking beer... Thanks scook 

By the way scook, how the heck did you know that obscure (to me) piece of information?
Do you ever sleep or just sit up reading the Sonar manual every night.... LOL

Not a very exciting explanation, it came from direct observation. I noticed some of the globally mapped key assignments were shown as unassigned when a project was not loaded. The assignments became populated after loading a project.

BENT

scook is responsible for several of the reverse-engineered alien technology modules in SONAR X15. No one is sure whether he's one of the grays, or whether he's just on good terms with them. 

I don't know how well know this is, but there seems a handy little App for smart phones on the play store called Shortcuts for Cakewalk Sonar, that looks a handy way to see shortcuts.

If we are talking about shortcuts, I dont understand how CW blocked Space from assigning (confirmed by support) I hope in new version CW rather solve this kind of bugs instead of bundling bunch of useless samples. I hope there will be also proper VST3 support as for now it is disaster.
