"Options" Tag - Is there a way to get a list of options tag variables/available fields?

I have a form with a checkbox field. I have all options for that field listed using the custom_fields tag pair and using the ‘options’ tag to list the checkbox options. I have decided to make the labels for those options links that would pop-up a window with more information. I can send the ‘option_value’ to the url for use with the ‘last_segment’ variable, but that does me no good in channel:entries to constrict the result.

Ideally, if there were an ‘option_id’ which was the entry id for that option, I could just use the ‘entry_id=” in channel:entries to pull it up in that information pop-up. But I don’t know what I have available because I can’t find the ‘options’ tag properties anywhere in the documentation.

Does an ‘options_id’ or something exist in that tag? I know ‘option_value’ exists and ‘field_name’, etc…

Or if there’s an easier way to get a link that will give me a pop-up window with the entry they just clicked… I mean if I could even somehow manufacture the url_title from the ‘option_value’, that would be enough, but I don’t know how to do that either…

Thanks.
