I have made a number of modules for e-Sword 9-10 in rtf and am just now learning some html encoding. I would like to have verse notes as pop-ups in Bible texts, similar to the notes in the "ESV with notes" module for my iPhone. The usual html coding is like this:
<span title="Literally <i>day one</i>"></span>
in which the note is seen on screen as "" and when one mouseovers  the comment about the "Literally..." shows up.
But this html coding does not seem recognized in my e-Sword modules.
Also, is there a list of codes recognized by e-Sword, such as <ref> as in <ref>Joh_3:16</ref> ? I have been able to experiment and discover some, but can a list be made available?
Some of my rtf modules are complex and have not converted well with the .dctx to .lexi conversion and I have had to do a custom conversion.
