There are others that can answer this better than I but here goes. AlphaX is a version of the editor Alpha that was developed specifically to run under OS X (10.4 or later) whereas Alpha itself was written for the classic Mac OS. AlphaX remains under active development. That said, there has not been an official release of a new version of AlphaX for quite some time. As I understand it, version 8.2 should be officially released soon, although many people have been working with stable beta versions for years.<BR>
<BR>
Alphatk is also a variant of Alpha but is written entirely in Tcl/Tk. (As I understand it AlphaX, and Alpha for that matter, are written in either C or C++.) Alphatk is available for Windows, Mac OS X and Unix although, to the best of my knowledge, is not currently under active development and hasn't been for a while. From a Mac user's perspective, the GUI of AlphaX is more mac-like than is that for Alphatk. Against that, Alphatk had some features that are yet to reach AlphaX, like the code-folding that started this thread.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>AlphaTcl is a library of Tcl scripts implementing most of the functionality of the text editor Alpha; AlphaTcl is not an editor in itself. A normal Alpha user will never have to worry about AlphaTcl: it is embedded inside Alpha. The functionality implemented in AlphaTcl is available from Alpha's menus like in any GUI text editor.<BR>
<BR>
The reason for having this library of scripts instead of implementing everything in C is that it makes Alpha modifiable and extensible. This wiki contains many examples of tweakings of Alpha: new functionality provided by power users, prototypes of new features being implemented, etc. <BR>

Much more information about the Alpha family of editors is available at <a href="http://alphatcl.sourceforge.net/wiki/">http://alphatcl.sourceforge.net/wiki/</a><BR>
<BR>
I hope this helps.<BR>
