Keynote is based on the
tree data structure concept, allowing "nodes" in a tree panel (much like the tree panel in Windows
file managers) to represent separate fields within a single text file. Individual documents within the tree can be edited in
Rich Text Format (RTF) or simple text (unformatted). Import and export of KeyNote files to and from TreePad files is fully supported. Each field is treated as a separate virtual document within the tree. KeyNote is
open-source software developed in
Delphi 3. As of October 2005, development of the original program had ceased. ==See also==
