F3 has been the "Find next occurrence" function under Windows in virtually every program almost since the very beginning. I use it constantly.
A variant on that theme is even used in screen reader finds, where "screen reader key" plus F3 does a screen reader find next.

The depths of denial one can be pushed to by outside forces of disapproval can make you not even recognize yourself to yourself.
