How to change citation style in amsrefs?

Question

I want to use the alphabetic style of citation in amsrefs, e.g. I want [Kr03] instead of just [1]. The documentation says that there is an option to do this, but I couldn't figure out how to invoke this option.

Sorry for the dumb question. I am appropriately embarrassed already.

Answer 1

You can use the alphabetic package option:

\usepackage[alphabetic]{amsrefs}
