Trash keyboard shortcut and selected text

Currently, the default Trash keyboard shortcut (delete) does not work when text is selected in the body of a received message. The keyboard shortcut should work when the selected text is immutable.

This is frustrating when copying a one-time password from an MFA email, forcing you to use your mouse to either deselect the text or select Trash from the kebab menu.

Alternatively, add a secondary shortcut that works in all contexts.
