I found some information about magic links in the answer to Add data.SE style “magic links” to comments, however I do not know if this list is exhaustive. Additionally, some useful suggestions were made in subsequent answers and comment which are of significant value to high activity users. I would be interested in knowing if any of these have since been implemeted.
I have tagged this as feature-request to highlight the other suggestions in the link I posted and to request that any additional magic links be documented in the FAQ. Feel free to retag as appropriate.
So in closing, is there a definitive list of magic links that are currently in-use on [SO]?
