-Below is the EBNF ([extended Backus-Naur form](https://en.wikipedia.org/wiki/Extended_Backus-Naur_form)) for snippets. With `\` (backslash), you can escape `$`, `}` and `\`. Within choice elements, the backslash also escapes comma and pipe characters.
+Below is the EBNF ([extended Backus-Naur form](https://en.wikipedia.org/wiki/Extended_Backus-Naur_form)) for snippets. With `\` (backslash), you can escape `$`, `}` and `\`. Within choice elements, the backslash also escapes comma and pipe characters. Only the characters required to be escaped can be escaped, so `$` should not be escaped within these constructs and neither `$` or `}` should be escaped inside choice constructs.
