Dear list members, When I needed arrows (e.g. for pyruvate ----> lactate or pyruvate <----> lactate I first tried on my own (\arrow, $\arrow$ $\ar$ etc.) without success. I then found "The comprehensive Latex Symbol List" by Scott Parkin and tried various combinations of \usemodule[modulename] and the commands listed, with our without $$. Some worked, some didn't. I do have what I need at the moment, but would like to know: 1. Is this the way to do it in Context? 2. Is there a recommended or particularly comprehensive module that covers a maximum number of symbols (I successfully tried "ams" and "wasysym" so far? 3. How do I find out what modules are available on my system? Thank you, Jörg PD Dr.med.
