Surround region with dollar sign ($) in Emacs

There is built-in emacs function for surrounding a region with parenthesis, as I found it here: https://stackoverflow.com/a/2952021/1635919. Is there an analogous way to surround a region with dollar ($)?

C-h f insert-pair tells that this function is able to surround sexp with any character, so how to bind surrounding with $ to M-$ as in the linked answer?

My Emacs: GNU Emacs 24.3.1 (i686-pc-linux-gnu, GTK+ Version 3.10.7)

Solution

  • You can duplicate what M-( does by looking at the insert-parentheses function. All it does is call insert-pair with hardcoded parameters, so you can analagously bind M-$ to the following function:

        (defun insert-dolla-dolla-bills-yall (&optional arg)
      (interactive "P")
      (insert-pair arg ?\$ ?\$))
