<blockquote type="cite"><span>I had a look at Vim documentation for this, and it's very confusing. As many things in Linux (sorry if offends someone) some sites says it's one way, others say different things. Not sure if there is a modern and simple guide for

<span>Yes am keen to do that, but first hoping we can get clear about color conventions and anything else configurable. Maybe then we can have a consistent approach across major text editors, if that is useful.</span><br>

<span>Another potential asset, if wanted and applicable: tooltip information. This information is retrievable via XML file, and indeed tooltip topic sentences are embedded in Python and Java APIs as well as X3D Ontology.</span><br>
