Templates allow you to prefill the content of an object- you can prefill properties and blocks in your objects.
This is very convenient if you have repeating workflows for which you want to set up predefined content because it saves you time, with no need to repeatedly set up each workflow. Templates are available for daily notes, pages, and custom object types.
Here is a Quick Tip video about templates to see them in action:

To create a template, go to Settings > Object Types > Choose your type > Scroll to "Define templates" > "+ New Template".
Your template is a blank canvas. You can do anything in a template that you can do in a standard object including block formatting and linking.
You can name your template in the box at the top of the screen.

There are many ways to apply a template you've created.
+ New button in the left sidebar.
You can directly apply a template from your keyboard too:
Cmd U (Mac) or Ctrl + U (Windows) and then the name of the template (that you defined when setting it up), press enter and you have created the object and applied the template all at once./<name of template> in any page and enter, which will also create the object and apply the template at once.
select the template you want to use.If you have a naming schema for your objects based on a date, for example, you want to name your weekly meeting Weekly - 2023-02-1, you can use a date syntax in the title. This will be replaced with the current date when applying the template. For the example above, you'd set the title of your template to Journal Entry - {date:YYYY-MM}-1. You can find more information about all possible date formatting options here.

You may want to set some templates as default, such as a daily note template or a colleague template for your Person object type.
Go to the Object type settings > Define Templates > press the star icon next to the relevant template. It will be applied automatically going forward.

Variable queries allow you to build templates that include smart queries, which work immediately without any manual adjustment.
