Great! That is just what I was looking for. I think it is working. Should I file a bug about the missing functions or is it already reported?

In Safari 1.3+, how do you convert a selection retrieved from window.getSelection() to a Range as specified in DOM 2 Ranges? In Mozilla you use getRangeAt() and in IE you use selection.createRange(). It seems that neither is supported with Safari. I was unable to find the W3C DOM way of doing it either. If I use createRange on the document I get an initialized textRange but not one that represents the selection. Safari documentation on this is sparse. Am I missing something obvious?
We should really support both of those!
Unfortunately, Safari 1.3 doesn't support either. But I suggest you try using selection.type to find out the type and then selection.baseNode, selection.baseOffset, selection.extentNode, and selection.extentOffset to get the four values you need to create a range.

That's awesome info and advice. I personally was totally unaware of those properties! I can now find a hint of them in the "source" (Darwin & KDE origin) but where might one look for documentation? I'm only finding this source code via Google at this point. I'm guessing it's defining the accessible properties of the selection object either in JS specifically or some generic IDL definition. Perhaps there is a KHTML doc somewhere outside of google space? Anybody know of a good KHTML/Safari doc that would cover this specialized stuff (simpler than the source :)?

const ClassInfo Selection::info = { "Selection", 0, 0, 0 }; /* @begin SelectionTable 19 anchorNode Selection::AnchorNode DontDelete|ReadOnly anchorOffset Selection::AnchorOffset DontDelete|ReadOnly focusNode Selection::FocusNode DontDelete|ReadOnly focusOffset Selection::FocusOffset DontDelete|ReadOnly baseNode Selection::AnchorNode DontDelete|ReadOnly baseOffset Selection::AnchorOffset DontDelete|ReadOnly extentNode Selection::FocusNode DontDelete|ReadOnly extentOffset Selection::FocusOffset DontDelete|ReadOnly isCollapsed Selection::IsCollapsed DontDelete|ReadOnly type Selection::_Type DontDelete|ReadOnly [[==]] Selection::EqualEqual DontDelete|ReadOnly toString Selection::ToString DontDelete|Function 0 collapse Selection::Collapse DontDelete|Function 2 collapseToEnd Selection::CollapseToEnd DontDelete|Function 0 collapseToStart Selection::CollapseToStart DontDelete|Function 0 empty Selection::Empty DontDelete|Function 0 setBaseAndExtent Selection::SetBaseAndExtent DontDelete|Function 4 setPosition Selection::SetPosition DontDelete|Function 2 modify Selection::Modify DontDelete|Function 3 @end
