TaskPaper knows about four things: projects, tasks, notes, and tags. As you type, these items are auto-formatted so that your lists are easier to read.
To create a project, type a line ending with a colon:
To create a task, type a line starting with a dash followed by a space:
To create a note, type any line that isn't recognized as a project or task:
This is a note that I added.
To create a tag, type the @ symbol followed by a name. Tags can optionally have a value in parentheses after the tag name:
Use Tabs to indent items under other items and create structure. Use Shift-Tab to undo this structure. Put these things together to make lists:
Groceries: - Eggs - Lettuce - Milk @priority(1)
Type your lists in this simple plain text format, and TaskPaper makes them look nice. TaskPaper doesn't force a particular system on you; it provides basic list making elements for you to use as you see fit.
