Keynote is a flexible, multi-featured tabbed notebook, based on Windows standard RichEdit control. It's always accessible with a single keypress, even if you work in another application. The basic idea in KeyNote is that you can include many separate notes within a single file. This means that you do not need to open several files - for most purposes it is enough to create only one file and hold all your notes inside it. With the addition of the tree-type notes, you now have a three-dimensional notebook: many notes within one file and a multi-level, nested pages within a single note. Optionally, KeyNote can encrypt your data securely using the Blowfish or Idea algorithms. Keynote's interface and behavior are extremely configurable.

Major features:

- RichText enabled editor, with many text formatting functions ad properties (font styles, colors, highlighted text, paragraph styles, bullets, numbered lists, etc.)
- Store many separate notes within one file; each note is displayed on its own, easily accessible tab. This is a much more convenient solution than opening several files on disk. Each note has independent font, color and editor settings.
- Choose between two types of notes: a simpler, editor-only note, or a tree-type note, which is a multi-level hierarchy of "branches", each with its own note. The two types of notes can be mixed freely within one file
- Tree type notes can be arranged horizontally (tree panel to the left of editor) or vertically (tree panel above the editor)
- Ability to create user-defined styles for text and paragraph properties
- Convenient keyboard shortcuts for all editing and file management commands
- And more ...
