Do you include "Back" and "Undo" buttons on every form?

Following on from including a URL, almost every form should have a Back and an Undo button which takes you back to the previous screen, or reverses the last action. This is just like Outlook (see figure below), it has a Back button to take you to the previous folder and an Undo button.

Notes:

• "Back" button should only be implemented if different views can be shown in the same window
• Don't put "Undo" buttons on non data entry forms such as a Print Preview form

The list of forms/URLs and the order in which they have been accessed should be stored in a DataSet held in memory (like IE) - not saved to disk.

For example:

Menu	Action	Undo	Back
Cut	Remember: Remember Text and Cursor Position Cut To Clipboard	Return to Remember	n/a
Save Record	Remember old values Execute procCustomerSave Close Form	Return to Old values	Reopen form
