Sometimes, one articles refers multiple times to the same reference. If you click on one of the reference indicators, you land in the references section. But how do you get back up to where you were before? One help are the secondary jump marks (e.g. a, b, c), but they also don't give an indication which of them you need to click. This should be changed.
Ideally, the solution should be as accessible as possible, not only when it comes to color and literacy, but also to the different writing systems.
On fa-wiki, the letter is already highlighted in bold ([[ https://fa.wikipedia.org/w/index.php?title=%D9%85%D8%AF%DB%8C%D8%A7%D9%88%DB%8C%DA%A9%DB%8C:Common.js&diff=21986171&oldid=20338370&uselang=en | code ]])
Highlight the letter that needs to be clicked to get to the original reading position.
The idea is the following:
 When a reference hint (e.g. ``) is clicked in wikitext, the page jumps to the appropriate reference.
 If the reference was used multiple times on the article, the jump mark leading back to your original position is highlighted.
 Highlighting is done through marking the letter as bold, and highlighting the background.
 Furthermore, the arrow also is a link to your orginal reading position (it currently already is a link if there is just one use of the reference, the change would be to now also have it as a link if you jump to it from within the article)
 Scrolling back up, the highlighting may persist
 There can always just one highlighted jump mark per reference
 Using an [[ https://www.w3.org/TR/wai-aria-practices/#link | aria role ]], indicate that this is the jump mark you came from for screen readers
