Undo, redo and delete

These work on every tab that has editable cards, graphics or tables (Title, Sprites, Background, Sound, Music, Text, Data and Score).

Hotkey	What it does
Ctrl+Z	Undo the last edit of the selected graphic, table, message, sound envelope or pattern. It also puts back a card, frame or background that was dragged into a new order.
Ctrl+Y	Redo.
Delete	Opens the "Delete this...?" confirmation next to the mouse pointer for the selected card or frame (Title, Sprites, Background, Sound, Text and Data tabs). A graphic editor with pixels selected uses Delete to clear those pixels first.
