undo-command

Arguments: window

Modifies window so that it is in the state that it was in just before the most recent edit was made by the user. The window may be (1) a standalone text-edit-pane, (2) the widget-window of a multi-line-editable-text, editable-text, or typable combo-box widget (as returned by calling window on the widget), or (3) a form window in an IDE project. In the IDE, the Edit | Undo command calls this function on the selected window.

When the window is a text-edit-pane (on the Windows platform), multiple calls to this function with no intervening text editing will undo successive edits, and redo-command must be used to redo each edit that was undone. For all other windows, a second call to this function with no intervening editing will redo the single undo that can be done.

In a form window, this will undo the most recent change to a property of the form itself, or undo the creation or deletion of a widget on the form. In other windows it affects text editing.
