The new menu search feature is a handy tool to avoid clicking in the navigation menu. I’m still getting use to having it, but it is becoming quite handy to avoid having to click multiple times if you know the menu item you want to find then you can type it in. Often this avoids 2-4 clicks which would have been the case in AX2012.
Here is a quick walkthrough the menu search.
