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 using 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
[X[1,2]]
where ‘X’ denotes the zero width space character.
