Integrate with core shortcuts

Problem/Motivation

Thanks for the useful module! It would be great if we could integrate this with core's shortcuts module, by, for example, adding a keyboard shortcut input in the shortcut link form.

Ofc this is not an easy task cause each user could configure his shortcuts and we would have to save the keyboard combinations (and whatever else) together with core's shortcut_field_data, for it to be picked up by the javascript code.

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
