Accessibility and keyboard support

[CodingDive]

Is your feature request related to a problem? Please describe.

I have to rely on my mouse to add bookmarks or open folders.

Describe the solution you'd like

Turn folders into semantic buttons and add a couple of keyboard shortcuts. E.g

new bookmark/folder = n

go up by a folder = arrow up

rename bookmark = r (when active)

move bookmark = m (when active)
