Shortcut key: ALT+BACKSPACE
The Undo command in the Edit menu allows you to “undo” previous editing actions—including find and replace actions. The number of editing actions you can undo is determined by the size of the Undo buffer. The default size for the buffer is 4K (kilobytes). You can use the Environment command on the Options menu to set the buffer to any size.
