I am fairly new to LyX. I have been disappointed to find that simple commands
defined via \newcommand and \DeclareMathOperator in the preamble (for example,
\newcommand{\sinc}{sinc}) appear as "evil red text" onscreen. In fact, they
look exactly the same as undefined (illegal!) commands. I got the impression
from the LyX manuals and user comments that LyX was pretty good at interpreting
and rendering user-defined commands. Have I misunderstood something, or am I
doing something wrong, or is there something wrong with my LyX installation?
(I realize there are several other threads with similar questions, but none of
them have a clear answer to this as far as I can tell.)
I am using LyX 1.6.7 on windows xp sp3.
