A few weeks ago, when pushing towards the new Azure Portal version 1.0 (aka GA at Microsoft), we added new shortcuts that can be activated with G+[key].
The full list of shortcuts is available on pressing ? key:
You may notice that we change shortcut for opening dashboard from H to D. However, H will still work. We didn’t want to take it away from people who already learned it, and got used to that. The same with New (formerly Create): the new shortcut N will work together with C.
BTW: If there is some keyboard, or focus related issue on the portal that is bothering you let me know!
