Wondering what a “hook” is? Hooks between documents can be created via `Hook to Copied Link` or the `Hook to New` command. > A hook involves a bookmark (a link) that is associated with (“contained in”) an item (call it “Foo”) and that points to another item (call it “Bar”), where Bar has a bookmark that points to “Foo”. So you can think of a hook as a pair of links, each member of the pair points to the other document. Here’s an example where a web page (on the left) contains a link to a text document (open in BBEdit) on the right. ![what are hooks](https://discourse.hookproductivity.com/uploads/default/original/2X/2/2464955a418b167e76f11a6a8fccca63407aed9a.jpeg) - On the left, you see that the name of the hook is _md- Issue 7993 BLOG- 2024-04 How to get a shareable link to an email .txt_, which is the name of the document on the right. - On the right, you see that the name of the hook is _[💡 How to use Hookmark with e-mail apps…](https://discourse.hookproductivity.com/t/how-to-use-hookmark-with-e-mail-apps/7746)_ Hooks make it very easy to navigate back and forth between two related resources. A common use case for hooks is when you need to take notes about a web page or PDF. Another set of use cases is when you are writing a document. You can hook your draft to: - the outline - the title file - your notes about the document - supporting information (e.g., PDFs and web pages) - key emails (e.g., from reviewers). That way, while you are writing you can easily consult the hooked information, and then get back to your draft — without needing to search or rummage through folders and lists. The easiest way to get the hang of hooks is by using the `Hook to New...` command. You can try it on this web page. This command creates a new ‘note’ (in the app of your choice) and hooks the new note to the original context (here a web page). ### See also these help pages: - [Hook to New](https://hookproductivity.com/help/hook-window/link-to-new/) - [Hook to Copied Link](https://hookproductivity.com/help/hook-window/link-to-copied-address/) - [Hookmark App Videos](https://hookproductivity.com/help/general/videos/) ### Questions?
