2.8 Sticky Function mode
Semantic Sticky Function minor mode displays a header line
that shows the declaration line of the function or tag on the
topmost line in the text area. This allows you to keep that
declaration line in view at all times, even if it is scrolls off
the “top” of the screen.
In addition, clicking Mouse-1 on the header line
opens a context menu that contains menu items for copying,
killing, or narrowing to that tag.
