One key/chord strikethrough & archiving

[propeeves]

Similar to the "ToDo" CTRL+ENTER, allowing CTRL+ALT+ENTER or something similar to strikethrough and archive bullets/nodes would be very useful.

This would require implementation of a "view archived" toggle somewhere as well, as ideally the CTRL+ALT+ENTER would hide the bullet as well.

EDIT: For live example of this, WorkFlowy has this feature as "mark as complete" I believe
