When using a syntax highlighting style which supports tasks, like Markdown or Simple List, Drafts recognizes task marks when the text [ ] or [x] appear in a draft and makes them tappable checkboxes – great for using Drafts as a light-duty task manager, for shopping lists and other needs.

These task marks typically appear at the beginning of list lines but can appear anywhere in the text.

Drafts ships with a scripted, smart action “Tasks” in the “Editing” action group (iOS only) which will toggle task marks for the selected lines, very similar to the behavior of the checkbox function in Apple’s Notes app. This action can also be installed from the Action Directory.
