Keynote (notetaking software)

KeyNote is a free notetaking and outlining text editor for Microsoft Windows, produced by Tranglos Software.

Overview
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.

Keynote NF as the improved successor
Development was resumed in 2006 by Daniel Prado, with a project called "KeyNote NF" (or "KeyNote - New Features") to distinguish it from other Google search results. Initially released on SourceForge, and presently on Github, it includes features such as alarm reminders on nodes. Current versions were 1.7.8.1 stable and 1.7.9.8 Beta. There was a long hiatus in new uploads, but on June 9, 2023, in a comment to Issue #602 on the GitHub site, Prado said that he was planning to upload a new version "very soon". At that time he also explained the hiatus and started responding to open Issues on the site.
