Formula for a back button

What is the formula I should use if I want to create a back button in my program, whereby the effect is the same as a Web browser's back button?
If you are in a view, the following formula will take you to the previous page: @DbCommand("Domino"; "ViewPreviousPage"), and if you want to have the button go to the next page, you should code: @DbCommand("Domino"; "ViewNextPage").

If you are in a form, the following formula will take you to the previous page: @Command([NavigatePrev]), and, likewise, should you want a button to take you to the next page, its code should be: @Command([NavigateNext]).
