From time to time, when new releases of SolidWorks add extra functionality to the existing tools, existing workflows change, creating some initial confusion for the users. The popular Shortcut Bar is a good example in this regard. Starting with SolidWorks 2012, when the Shortcut Bar is invoked with the “S” hotkey, by default it also turns on the input field of the Command Search. As a consequence, pressing “S” again will not only turn off the Shortcut Bar but will also insert text (the “s” character) in the Command search field.
Please watch this video for a demonstration about linking and unlinking the Shortcut Bar to the Command Search and, after that, choose the solution that is right for you.
