Make hotkeys trigger batch operation when multiple messages are selected

[szotsaki]

Expected behavior

Select multiple e-mails then on hardware keyboard press M (for move). It asks in which folder to move them.

Actual behavior

It moves only one mail instead of all of the selected. If I use the "right click" menu, then all the selected e-mails are moved.

Environment

K-9 Mail version: 5.600

Android version: 8.0.0

Account type (IMAP, POP3, WebDAV/Exchange): IMAP
