Apart from inserting links to specific webpages, you can also use links in Writer to navigate to other Writer documents, specific pages of a document, a comment, a particular part of a document or even headings.
Here's a quick rundown of the different linking options in Writer:


Now to add a navigation link for your heading, all you have to do is to choose it from the headings list and click Apply.

Additionally, you can also generate a URL for your headings. To do this, right click on the heading and click on Get Link.


Images in your Writer document can be made clickable using the insert link option. To set up image links:
Right click on the image.
Enter the URL and click Apply.
These images, when exported as PDF, will appear clickable as well.
Refer to a particular version of a document by generating a version link. To do this, go to Version History, click on the more options button next to a particular version and select Get Link.

Happy Writing!
