Invoke the Snippets view by selecting "Window Menu-> Show View ->
Others". In the Show View window, select "General -> Snippets" and
click OK.
Drag the view to where you want it in the perspective (I usually place
it below the Outline view)
Adding a snippet is as simple as control clicking in a chunck of text
and selecting "Add to Snippets" you will be given the oportunity to
edit the snippet, add it to a group, and specify replacement
variables.
I've created a WebObjects Snippets group and have the following:
webobject element
webobject container
webobject open
webobject close
WOComponent template
I'm sure you will come up with others.

Example templates:
<webobject name="${cursor}"></webobject>
<webobject name="${cursor}" />
