Add option for jumping into the hover floating window on the first press.

[LarssonMartin1998]

I get annoyed that it takes so many key presses to close the hover window. Either I have to move my cursor which I don't want to do most times, resulting in me just moving it back. Or, I have to press my keybind to jump into the window again and then q to close it.

This is an option which just moves the cursor directly into the window when you open it, this way you can close it using q directly.

At first I thought about letting q close the window without jumping into it and let that be the option. However, then it can't use a buffer specific keybinding, I think this is the better choice. However, I'm open for suggestions, this at least fixes my issue.
