/* Entry/Undo and Redo
|
|
*
|
|
* GtkEntry can provide basic Undo/Redo support using standard keyboard
|
|
* accelerators such as Control+z to undo and Control+Shift+z to redo.
|
|
* Additionally, Control+y can be used to redo.
|
|
*
|
|
* Use gtk_entry_set_enable_undo() to enable undo/redo support.
