Comment 2 for bug 728081

Patch tested successfully on Windows XP, Inkscape trunk revision 11129. Thanks, Jessica!

Now we need to associate the actions to shortcuts, and the list is already a bit crowded...
I'd use Ctrl+Alt+H (hide) and Ctrl+Alt+L (lock), but the first one is already used by org.inkscape.typography.previousglyphlayer. If we consider that core Inkscape shortcuts have priority over extensions, we can also modify the previousglyphlayer shortcut...
