Link to a question, answer or comment

Question

In writing a question, answer or comment, how can I include a clickable link to cross-reference another question, answer or comment?

No, those things are indeed not mentioned in the help center, or any documentation, and can be found only by trial and error, or searching here. Many of them are mentioned here — Shadow Wizard, Commented Jan 5, 2016 at 21:23

Link to a question or an answer

Go to the question/answer that you want a link to.
Look at the end of that posting, before any comments or subsequent answers.
Click share near the lower left corner of the text. ^∇
Something like this will pop up:

share a link to this question
http: //meta.stackexchange.com/q/272427/313009
close
Copy http: //meta.stackexchange.com/q/272427/313009, using your mouse or Ctrl+A Ctrl+C.
Return to the question, answer or comment that you are writing.
Paste what you just copied, using your mouse or Ctrl+V.
Make sure that the resulting http: //meta.stackexchange.com/q/272427/313009 is surrounded by spaces.
That should do it, in a basic way.
More information is available by clicking links near the top left corner of the area where you are writing. If you don't see links , click the ? near the top right corner of your writing area.

Go to the end of the comment that you want a link to.
