You may sometimes want to write text that looks like Org syntax, but should really read as plain text. Org may use a specific escape character in some situations, i.e., a backslash in macros (see Macro Replacement) and links (see Link Format), or a comma in source and example blocks (see Literal Examples). In the general case, however, we suggest to use the zero width space. You can insert one with any of the following:
C-x 8 <RET> zero width space <RET> C-x 8 <RET> 200B <RET>
For example, in order to write ‘[[1,2]]’ as-is in your document, you may write instead
where ‘X’ denotes the zero width space character.
