[Feature] Shortcut (Switch Cards)

[mezhgano]

Thanks for the great application.
I think it may be useful to implement a shortcuts for switching cards back and forth, for example:

PGUP - switch to the next card
PGDN - switch to the previous card

Or, maybe WHEELUP AND WHEELDOWN

I know we can just use preview window, but sometimes when playing with margins and styles to match cards together it will be handy.

Thanks for the suggestion! Just to make sure I understood you correctly: You want to be able to do the following switching not only with your mouse, but also with keyboard shortcuts, right?

Yes, exactly
