Yes, I've been retraining myself to use Ctrl-F instead of F3 for Search.
One thing I miss is that in 4.3, I could do Ctrl-F, type my query, hit Return, then keep hitting F3 to repeat the search.
Now that I'm using Ctrl-F in 5.0, there doesn't seem to be an easy way to go to the next occurrence (not Return, not F3). Is there one?
