The example above demonstrates a typical use of Gemini: some headers act as direct links (as a result of having HeaderURL parameters) while others open the tree to display their text-links. In this instance, there is no apparent difference between the two (other than the hand-cursor if the target browser supports it), but you might prefer to use different images for headers that act as direct links as an indicator to visitors.

StickyHeaders is set to 'yes' so that the last-clicked header remains 'pressed', and Centered is set to 'no' so that images and text-links are left-aligned. A larger font is in use here to demonstrate that Gemini's reactivity stays consistent regardless of font size.

Headers do not display statusbar messages here, but each text-link does, using the Message parameters. The Sound option has been switched off, so the three other sound-related parameters can be removed.

In the above example, the Selector parameter is set to 'bars'. The example below is almost identical, but Centered is set to 'yes' and Selector is set to 'lines'.
