The search box can open by Ctrl+F and start searching by hit <Enter> with some words.
To move to next search results, I need to press <F3>.
This is very annoying.
Please unify key mapping, <Enter> or <F3>.
I think this is because the search box disappears after the first search.
Why don't you keep showing the search box to avoid bothersome?
I prefer vim-like searching though:)
