This simple macro produces a usable internal link whose text changes whenever you mouseover it.

version.extensions.hoverlinkMacro={major:1,minor:1,revision:0};macros.hoverlink={handler:function(a,b,c){var d,l=Wikifier.createInternalLink(a,c[0]);
l.className+=" hoverLink";insertElement(l,"span",null,null,c[1]||c[0]);if(c[2]){d=insertElement(l,"span",null,null,c[2]);
d.style.display="none";}l.onmouseover=function(){if(this.childNodes.length>1){this.childNodes[0].style.display="none";
this.childNodes[1].style.display="inline";}};l.onmouseout=function(){if(this.childNodes.length>1){this.childNodes[1].style.display="none";
this.childNodes[0].style.display="inline";}};}};

This uses the << choice >> macro's parameter order - the destination passage name comes first. Then comes the visible label, then the hidden label.

Usage example: <<hoverlink "CryPassage" "Stand and fight, guns blazing" "Sit down and have a cry">>

For obvious reasons, this won't work on iPads!

Implementation details:

* The link has a class of "hoverLink" in addition to the standard internalLink/brokenLink classes.
* Each text label is a <span> inside the <a>, and the mouseover and mouseout events make one or the other visible.
