Response to keyboard keys

[NexiusTailer]

Basically it already a thing, but it behaves just like in browser surfing a website, which is not always expected using native application.

Let me explain:
If you will press arrow up/down in a server list, it wont automatically select a server and every press will just go up and down like scrolling a webpage. Selecting a server is only possible pressing tab key like in web. And if you press enter after tab key, it will be really selected (like with clicking by mouse), but still enter is not a key which can select buttons in dialogs without press tab before.

I decided to create an issue here anyway, because the problem described in discord already scrolled up too far away and would probably be forgotten.
