Hello, Is there a way to define a macro that has different behaviors depending on export backend? I have macros that use the @@latex:foo@@ syntax, but in that case I "foo" is supposed to be literal latex. My use case is this one: I have a link to a custom id, and I want to export it as [[#id]] in latex and [[file:file.org::#id]] for html *before* link resolution happens (so that the custom id in the latex export is substituted with the correct label). Is this possible? Thanks, Alan -- OpenPGP Key ID : 040D0A3B4ED2E5C7 Monthly Athmospheric CO₂, Mauna Loa Obs. 2017-12: 406.82, 2016-12: 404.42
