Slab's table of contents helps you organize the content in posts and makes them easier to navigate. Whenever you create a header in a post, the table of contents will be automatically generated with links to the header.
There are 3 ways to create a header:
Using the command editor
Type /heading and select from the 3 sizes available.
Using the selection menu
Select some existing text and choose a type of header from the drop-down menu that appears.
Type #+Space to insert an H1 header, ##+Space to insert an H2 header, and ###+Space to insert an H3 header.
The table of contents will then be accessible in the left-hand side of the post. You can click on the three-lines icon to show or hide it. You can also click on any of the headers to jump directly to that section of the post!
