I had no idea shift+F3 was there. If I even thought to look for such a feature I would assume it is in the right-click context menu and wouldn’t need a shortcut for it since I would use it once a decade. Now I wonder what kind of environment you work in where that is needed (and I work in an environment where a critical application requires Caps-Lock on for any extended usage).

This shows the problem with people who think the features in Office apps that they don’t use are bloat. If you made a new app using the 80% of features all the users regularly used, you’d discover you need 100% of those features because 20% of the users use a different set of obscure features.
