[wishlist] keyboard shortcuts

[janxkoci]

Hi, I really like your app and I think it could benefit from some keyboard shortcuts.

For instance I think it would be very helpful if we could focus the search field in Processes by pressing e.g. Ctrl+F.

Also switching between different views would be cool. For example something like Ctrl+1, 2, 3 for switching to respective views could work really nicely 😃

Thanks for considering this feature, but your app is really great already :)
