The task notation syntax is a Markdown extension to write down tasks:

Its most basic form is:

   
* [ ] My task name


which renders as follows:
  • My task name


SilverBullet allows you to simply toggle the complete state of a task by clicking the checkbox. It also allows for querying tasks as Objects#task. For instance:

${query[[from index.tag "task" where page == editor.getCurrentPage()]]}
