Make arrow buttons work within search box
Every time I use a search bar by keyword `s` to find a group or project, I can't use `up` and `down` arrows on keyboard to navigate between results. It's really annoying as I can't quickly jump between projects/groups without using cursor
Desired behavior:
1. Use `s` shortcut to focus on search bar
2. Use `up` and `down` keys to select a project or a group
3. Press `enter` to navigate to selected project or group.
