I have downloaded the elsarticle template (Previously installing the package), and just opening and executing the raw template (As downloaded from El Sevier, without editing) I have two commands shaded in red: "\ead" and "begin{keyword}". It says "Unrecognized command" and "Unrecognized environment" respectively.
However, when executing the code, I get no errors. Why is this happening?
I'm supposed to ignore this errors, because my code is executing normally, but these errors make me to suspect that Im doing something wrong.
Thanks in advance!
