Merge lp:~canonical-dx-team/unity/unity.fix-646712 into lp:unity

[Mirco Müller]

This branch makes the superkey-overlays show up on the launcher, if the Super-key is held down. The first 10 icons get labels and trash-can and workspace-switcher get special labels.

[Didier Roche-Tolomelli (didrocks)]

160 + if (_super_show_launcher)
(and following)… Can you please avoid by any mean to hardcode the keys?
The places can set dynamic values in their .place file for that for instance, so it won't scale. We will probably change the "t" and "w" shortcut as well. So having them in one place is better.

if you go over the model, I think you can get both the index and the shortcut.

review: Needs Fixing

[Mirco Müller (macslow)]

I didn't know about the dynamic-mapping for trashcan, workspaces-switcher and places.

Approved!
