Is your feature request related to a problem? Please describe.
I'm always frustrated when I have to delete pictures in the picture viewer.
For every deletion I have to click the dot menu (...). Then I must move the mouse pointer to the delete-icon. Then I must click the icon.
This are three actions for one deletion. It will be much more practical to do this with only one key click.
I have thousands of pictures from my smartphone automatical upload. There are always many double pictures or unsharp pictures to delete.
Browsing the pictures with the arrow keys and deleting with the del-key will be working like a charm.

Describe the solution you'd like
Enable a shortcut to delete pictures with the delete-key.

Describe alternatives you've considered
None.

Additional context

Start by locating the picture viewer's keyboard handling and the existing delete action. Check how the Delete key interacts with picture navigation and confirm that a picture can be deleted with that key while browsing, with the existing deletion behavior preserved.
