Is your feature request related to a problem? Please describe.

There is no default gesture for reporting details summary.
NVDA+d will report a long description if it is available, this is rare.

Describe the solution you'd like

Make NVDA+d report long description then details-summary, (if either is available).

Describe alternatives you've considered

Leave the command unassigned.

Additional context
