Code review comment for lp:~unity-2d-team/unity-2d/shortcut-hint-overlay

I don't think having untranslatable strings is acceptable.

If we can't have
ListElement { defaultKey: "Super (Press)"; description: u2d.tr("Open Launcher, displays shortcuts."); gconfKey: "" }
because of that Qt bug i suggest we do this

Switch can to using
text: u2d.tr(description)
and then add somewhere in the file
    function dummyFunction() {
        u2d.tr("Open Launcher, displays shortcuts.")
        ...
        ...
    }
This way we trick po/update-unity-2d-pot to extract the descriptions into the .pot file and things are translatable again
