A way to navigate entries using only the keyboard when entering the Git Graph view

[jraygauthier]

Describe the feature that you'd like

Currently when I enter the Git Graph view, in order to get access to an item, I need to use the mouse to select this item.

I would like that there is a way to avoid using the mouse and that the full interface is accessible with only the keyboard. This would allow users to be much more productive.

A simple way to achieve this would be to have an option to auto select the HEAD item when the view load. It would then be possible to navigate the items using only the keyboard arrows (Up/Down). Once issue #864 is fixed, users would also be able to get access to the nice contextual menu through the "Menu Key" or Shift+F10 which would allow us to launch actions on the item (e.g.: "Copy Commit Hash", etc.).
