Thanks @galen: aTbRef basically grew out of me learning how to use Tinderbox and as HTML ex[port wax easy it seemed pointless not to share. A bit more on the target/title/class link terms…
The link type is really a internal thing stretches back to Tinderbox’s early days pre-database blogs. You don’t have to use link types. They were a bigger deal in the early days of (pre-Web) hypertext. Some folk like them, others don’t see the need. They’re there for when you need them. By default links are un-typed (OK, type ‘untitled’) and as such on maps have no link label. There’s no reason external links (i.e. ‘web links’ in Tinderbox parlance) need a link type but they are still links and sometimes it might be useful to be able to differentiate them from other links. Or, you might have web links that are basically a look-up, so might be a ‘glossary’ or dictionary’ type if that helps.
The Target, Title and Class relate only to HTML use, setting attributes of the exported
Title is perhaps most obscure and also less used now. Its role is not to duplicate the anchor text of the note but to provide additional info for the HTML link and for this reason if a link has a ‘title’ attribute web browsers will show it as a tooltip when you mouse over a link.
Class sets the HTML link’s
class attribute, i.e. the CSS class used to style the link. It may be that you want different types of styling for different links - or different type of links. Currently, class must be set manually per link - it is not possible to make all links of a given link type use a given CSS class.
