Add keyboard shortcut to toggle notifications on issues, MRs, and work items
Summary
Toggling notifications on or off is a common action on items using that feature, currently issues, epics, work items, and MRs. A keyboard shortcut would provide an efficient way for users to act on this from anywhere on the page without requiring mouse/tab focus.
Proposal
Depending on how we frame this action one of two shortcuts would be appropriate:
Subscribe/Unsubscribe ShiftS This is how this is defined in the docs today.
Enable/disable notifications ShiftN This is how this is presented in the issue/MR UI today.
