Are the function keys used in Unity?

Are the function keys (F1, F2, F3… F11 F12) used by default for anything within Unity?

I was thinking that I would like to set up my game to bind a screenshot button to a function key, but then I realized I should check if Unity already uses any of the function keys for anything.

Either within a plain Unity app, or within the editor, does Unity use any of them?

F9 opens the Profiler by default in the editor. That can be customized in the Shortcuts view though.

Other than that I don’t think any of them are used, except for F2 being used for renaming things in the hierarchy and project views.

You’ll find all the keys and shortcuts used by Unity in Edit/Shortcuts…

Okay, that answers the question about the editor.
What about default features in a Unity game? If I created a “blank” game without changing any of the default settings, would the function keys be set to do anything within the game? Are there certain commands that come bound to them?

No, they’re all unused.
