By pressing this button, a marker is placed where your caret was
last put in the window. This marker shows where menu 1 will go.
The marker looks like this:
<-- #Menu_1 -->
You can delete this by highlighting and you can
cut and paste it elsewhere on the page. If there is no marker,
there will be no menu 1 shown on the page.
Menus
You have a choice of one or two menus on your page. Both will
work together in synch as you navigate through the site. However,
this gives you the chance to have both a vertical and horizontal
menu on the same page and showing in different places. A practical
application being that many sites have menus at the top or mostly
on the left. This also allows you to have a horizontal menu at
the bottom of the page to allow users of the site more scope in
finding their way around - especially on deep (long) pages.
A second marker can be used to incorporate a text
based menu to allow for easy spidering of the web site by the
search engines.
