I need to be able to more efficiently change a link to the heading text the link points to, without having to do cumbersome steps.
This a workaround for the more ideal feature that, as of 2020-05-22, has yet to be implemented by Google: How to insert links to headings in Google Docs without brute force (incremental completion and narrowing)
See the image below which explains the problem. Below that image, see the steps to reproduce this problem:
I do not want to workaround this by having to edit the URL text, or have to use method of adding links to headings using CTRL+k, as that is taking up too much time when this operation is done many, many times during an editing session: It is cumbersome because it forces you to scroll down a list of all headings in the document, versus driving to it directly, and that list of headings can be quite large. As the number of headings increases, it becomes impractical to scroll down that list every single time to find the heading.
