STABLE version -- 4.3.9.248

[Admin]

There are a lot of sites, where search fields have no "Search" button. So, when I paste text to search into search field, I need to hit Enter. I think, it will be useful to gesture "Enter" button, without using keyboard.

This feature should be made universal(can simulate any key), otherwise there are too many keys to support.
We may refactor this feature in the future.
