TodoTxt

A .todotxt file is a plain-text task list in the todo.txt format. Datalith gives it a dedicated editor: filter, sort, complete, and nest tasks.

A task line

(A) 2026-01-01 Ship the docs Vault +project @context due:2026-02-01

A line is made of optional parts:

• Priority (A): a single letter from (A) down to (Z).
• Completion x: the first character when a task is done. Completion date may follow.
• Date YYYY-MM-DD: creation date after the priority.
• Description: the free text of the task.
• Project +name and Context @name: tagging tokens in the description.
• Extensions: extra key:value pairs such as due:2026-02-01.

Subtasks

Indent a line to make it a subtask of the task above. While editing a task, press ⇧↩ to add a subtask below it, and use the disclosure arrow to collapse a parent.

Done

Marking a task complete prefixes it with x. You can filter them out, or sort to push them down.

Using the editor

• Press ↩ on a task to toggle it complete.
• Press ⇧↩ on a task to add a subtask.
• Press ⇧⌫ on a task to delete it.
• Press ↑ and ↓ to move from one task to another.
• Press Cmd/Ctrl+F to search a file.
• Filter to view all, active, or completed tasks.
• Sort by created date and toggle the direction.
• The inline search box matches descriptions, priorities, dates, projects, contexts, and extensions.
