Feature Request: keyboard navigation (next/previous item)

[PanBartosz]

I could not find any way to navigate between items using keyboard shortcuts. Maybe it is a good idea to add them? For example arrow keys for previous/next document on the list.

The shortcut feature is already implemented. You can use three shortcuts to navigate document. Taking the Next button as example, you can use ctrl n, 'arrowdown' and 'arrowright'. Is this helpful?

It will be more convenient to have left-hand navigation shortcuts. This modification makes a more fluent workflow, when working with sequence labeling job. We can keep left hand on keyboard and right hand on mouse selecting texts, without moving around.

Maybe with a custom key config? @BrambleXu
