Can someone please tell me what these functions do?
```
function CodeHighlightOn(elem, id)
{
var target = document.getElementById(id);
if(null != target) {
elem.cacheClassElem = elem.className;
elem.cacheClassTarget = target.className;
target.className = "code-highlighted";
elem.className = "code-highlighted";
}
}
function CodeHighlightOff(elem, id)
{
var target = document.getElementById(id);
if(elem.cacheClassElem)
elem.className = elem.cacheClassElem;
if(elem.cacheClassTarget)
target.className = elem.cacheClassTarget;
}
```
The only thing I could think of is to toggle some classes, but I can't seem to find some real world example out there. This javascript code is included on every export, doesn't matter if you've src/example blocks in your org file or not.
Thanks
