Keyboard shortcuts for lenses should be customizable in System Settings

[Jeremy Bícha]

The keyboard shortcuts for opening the Unity dash to a specific lens should be customizable in System Settings>Keyboard>Shortcuts. This is useful for tweakers or for those who just want to see a list of what keyboard shortcuts are available (*discoverability*) [1]. Also, as we get more and more custom lenses, it's nearly unavoidable that multiple third-party lenses will try to use the same shortcut; the user should be able to manually fix that if desired.

[1] Yes, there's the keyboard shortcut overlay but there won't be enough room for all shortcuts to be listed. Also, currently the overlay doesn't do high contrast so the System Settings view would be better for those who need high contrast.

What we don't want is people needing to edit system files and have those changes lost whenever there are updates to that Unity lens. http://www.iloveubuntu.net/how-easily-add-preferred-keyboard-shortcuts-unity-lenses

This can be done by adding the appropriate .xml to /usr/share/gnome-control-center/keybindings/ GNOME Shell puts their extra shortcuts (like 'Show the Message Tray') in the System category. And then the Unity lens specification would need to be updated so that developers use that method for keyboard shortcuts instead of the /usr/share/unity/lenses Shortcut= syntax.

Core Unity developers will not be adding any new features to Unity 7 at this stage. As part of the big bug clear up for 16.04 this bug is being marked as Opinion. While this bug is affecting you, and potentially others, we are not considering working on it so it won't get fixed by us. Other developers are free to pick this up and work on it. Sorry that we can't offer you help at this time.
