Include current app shortcuts?

[peteruithoven]

Apps like Files have a lot of useful, but hard to discover shortcuts. In some cases we could add shortcuts to tooltips or menu's but shortcuts like alt+up, for navigating to the parent folder, doesn't even have a button.

Could we extend this overlay to include a list of app shortcuts? It's probably not scalable to show this for all apps, but maybe we can list just the shortcuts for the current app. (Beside the system wide shortcuts) The current app being the app that had focus before the shortcut overlay was opened.
This way we re-use a known shortcuts screen and we don't have to add extra interface (help screens) in each app.

One of the challenges is probably to have apps make their shortcuts available to the shortcuts overlay?

I think this would need some api to expose shortcuts, maybe granite is a better place for this. An app can just add a key value pair of shortcut and function. It will be upto overlay to render it.

Using the shortcut-overlay would ensure consistent appearance and shortcut although it would mean each app implementing a dbus interface (presumably) for its shortcuts.

I'm going to mark this as "Blocked" since there is currently no standard way for apps to expose shortcuts externally

Another possibility would be to have shortcut-overlay widget in Granite and decide a common shortcut to which apps could respond in order to display their shortcuts using that widget.
