Purpose: describe how the supertext extension is useful.
I think this is the "Supertext" that Kitten is talking about...
What: text widget with undo Where: http://www1.clearlight.com/%7Eoakley/tcl/supertext.html Description: Supertext widget with builtin undo. Updated: 06/1998 Contact: mailto:[email protected] (Bryan Oakley)
The text widget as of 8.4a5 has an undo/redo mechanism builtin. See http://www.tcl.tk/man/tcl8.4/TkCmd/text.htm#M72 and http://www.tcl.tk/man/tcl8.4/TkCmd/text.htm#M89 for the documentation. See http://www.tcl.tk/cgi-bin/tct/tip/26.html for the TIP that implemented it.
