Slideout tabs can be a great way to give the user quick access to information or navigation without taking up valuable screen space. Tabs like the one at left can sit in the margin of the page and slide out when the user needs them. The tab I've implemented holds the links to the rest of my DHTML examples.

Example
Click here or on the tab on the left edge of the screen to see the slideout tab in action. Note how the arrow points in or out depending on the menu's position to give the user a cue about how the tab works.
