Nested tasks, also called "subtasks," are a way to indicate a hierarchical relationship between tasks. Usually, the parent task will have subtasks that enumerate "steps to accomplish the parent task" or "dependencies that must be met to complete the parent task." That might sound kind of complicated, but in practice, the use case of subtasks is pretty simple:
Walk the dog 🦮🚶
Pack a plastic bag 💩
Help Potter pup don that outfit he insists on wearing out on Fridays 🍀
Pack extra water 💦
Buy more treats 🐶
Prefers vegan cow hides 🐄
Also tolerates vegan piggie bites 🐷
Set off toward end of rainbow 🌈
In this most common form of a parent task with subtasks, the parent task can't be said to have been "completed" until all of its children have been marked completed.
Let's run down some of what you can do with subtasks when viewed in Notes view or Jots View mode.
The easiest way to create a subtask is to create a task (i.e., by pressing
 followed by a space) that follows your desired parent task, then hit the
tab key so that your task is indented. Note that, to indent the task so it becomes a subtask, your cursor must be at the beginning of the line. If your cursor is anywhere else in the task, then the
tab key won't indent it. So be sure your cursor is at the first position.
After you create your first subtask, then pressing enter will automatically create another subtask at the same depth.
If you're on mobile, use the highlighted toolbar icons to create or remove subtasks:
You can use the usual hotkeys for reordering subtasks:
Reordering subtasks using the macOS hotkeys. On PC, the ⌘ key correspond to "Ctrl"
You can expand or collapse subtasks by using the
ctrl-, hotkey when your cursor is in the parent task, or by using the expand/collapse arrow positioned to the left of any task with subtasks:
Tasks can be expanded or collapsed by clicking the arrow at left, or using the Keyboard Shortcuts
All of a parents subtasks will travel with the parent when dragged:
Treats and treat subtasks dragged down the list. This could also have been accomplished by using the task reorder hotkey when cursor was on the parent
Works the same way as completing normal tasks: by clicking box or using the hotkey (ctrl-space) to mark it complete. Nothing to see here, move along folks. 🙂
If the parent task is completed, it's curtains for all of its subtasks:
When a parent task is completed, all subtasks are marked as complete
This saves time when your subtasks are too small to bother individually checking off. Often times, you just want to have the subtasks present for the sake of completeness.
