List of templates?

When I build macros (3.5e by the way), there is always a "Template" attribute at the beginning. I understand the purpose, The engine must know what we are doing. I was wondering if there was a list somewhere that explains all the possible types of templates there are? For instance, I'm creating Chat Menus, I read the page about Roll Templates , but it only talks about the Default tempale and how special it is. Are there any other values the Template attribute can take? In some examples I've seen the attribute was set to a colour, not the usual "default" value. Was that for 5e only? I see that the Default setting for roll templates places everything in two columns, and that the first column is always bold. Can I decide to have one column that is not bold and not right aligned (if I do not use the "=" I get a single column but it looks weird)? How about  three columns? Can I tell it not to use bold in the first column? etc. Thanks!

Templates are created with each character sheet, so the best way to find out what templates exist is to look at the wiki page for that sheet if there is one. (Failing that, you can look through the html page of the sheet on github.) The default template is special because it is the only one that is available regardless of what sheet you are using - every other rolltemplate is created by the sheet's author. Some sheets have no rolltemplates, some have one, some have multiple. But it's all dependent on the sheet itself. Beyond that, the default rolltemplate is always available.

Thanks, it makes sense that Roll Templates are dependant on Sheets, thanks for clarifying this.
