Therefore, each has its own undo memory. If
you are in a particular frame and try to undo a frameset alteration, such as adding a new frame to the set, it
won??™t work. To reverse an edit to the frameset, you have to select the frameset and choose Edit ??? Undo, or
use one of the keyboard shortcuts (Ctrl+Z or Command+Z). To reverse the creation of a frameset, you must
select Undo twice.
Targeting Frame Content
One of the major uses of frames is for navigational control. One frame acts as the navigation center, offering
links to various Web pages in a site. When the user selects one of the links, the Web page appears in
another frame on the page; and that frame, if necessary, can scroll independently of the navigation frame.
This technique keeps the navigation links always visible and accessible.
When you assign a link to appear in a particular frame of your Web page, you are said to be assigning a
target for the link. You can target specific frames in your Web page, and you can target structural parts of a
frameset. In Dreamweaver, targets for typical text or image links are assigned through the Text and Image

jump menu behavior (see Chapter 12).
