A minor correction to Matt's example:
| together, listKey and listValue resolve as ....
| <option value="{listValue}">listKey</option>
Actually, the listKey is assigned to the option value, and the listValue
is the option display. I know the names seem confusing, but that
actually makes sense -- the key holds the data you're interested in and
the value is the display stuff. Since you're interested in the key, in
HTML that data goes in <option value="...">. Besides, that's how 1.3
works :)

here's a quickie rundown:
* theme -- the prefix of the velocity template, defaults to
templates/xhtml
* template -- the name of the velocity template
together theme + template form the template to look up.
* label -- the ognl resolved value to the left of the select list. will
be resovled against action.getText(...) if it's there
* name -- name of the select input field <select name="...">
* value -- the ognl resolved value for the select
* list -- the collection or array that contains the values for the
select tag
* listKey -- the ognl expression to be applied against each element of
the collection / array specified in the list attribute
* listValue -- the ognl expression to be applied against each element of
the collection / array specified in the list attribute
together, listKey and listValue resolve as ....
<option value="{listValue}">listKey</option>
* defaultValue / defaultKey -- default values for the list
* multiple -- whether or not it's a pulldown list of a select list
* size -- if it's a list box, how many elements to display
This is off the top of my head so I might be a little off.
