I have a silenced codeblock, that I postprocess to push the result (a password) onto the kill-ring, and then returns "Password copied" (showing in the status line). This works very nicely. I'm now looking for the cherry on the cake: I'd like to render the #+CALL as a link, e.g. something like, [Copy the secret thing]. Clicking/following the link would execute the call and my password ready to paste elsewhere. Feasible?
