In a recent discussion on the mailing list, I noticed that Joris mentioned
Arrows of arbitrary lengths can be obtained by entering them
directly as symbols. Using the Emacs-look and feel,
this is done as follows:
C-q rubber-rightarrow-25 return
I am very interested, but couldn’t make the code above work on my laptop because of my lack of Emacs experience. I would be very grateful if anyone could explain how to obtain arrows of arbitrary lengths as Joris said, especially on macOS. Thanks in advance.
