In edit mode it is pretty hard to actually activate the tray for a certain block while tabbing.
We should improve the accessibility.
Steps to take to activate the tray:
1) Activate edit mode
2) Tab through contextual links buttons
3) Press enter to show the contextual links
4) Tab until you hit 'Quick edit'.
5) Press enter on the 'Quick edit' link.

Even better would be that in edit mode, when tabbing (through the blocks) you actually tab through two links per block:
the first being Quick edit, the second being the contextual links link, that gives you the option to show all other edit links that navigate away from the page (advanced links).
This would also be more in line with what you do as a non-disable person, because they can just click the dotted outlined block directly.
In non edit mode, it would be oke to show the 'Quick edit' link again in the contextual links list per block.
From Wim's comment in #164 in issue :
Accessibility: This does not yet meet the accessibility gate! Tabbing should jump from one editable to the next one, but it just does the "normal" tabbing. This should use the TabbingManager to constrain tabbing to just the contextual links, just like Contextual Links module does. But also… and perhaps more worrisome… this is then overriding that portion of Contextual Links? Why?
