# [TxMt] LaTeX "at" symbol (was: Brilliance Black, Twilight etc ...)

Hi Alain,

This has nothing to do with themes. Themes do determine how things
are colored, but it is the syntax that determines what *can* be
colored by assigning scopes to things, and your questions all relate
to things possibly not being scoped properly.

Shouldn't there be a \ in front of :=13 ?

All these are essentially the same question, and it has to do with
dealing with @. At the moment we are not allowing @ as part of a
command. I thought it was a character to avoid in LaTeX. Can you
explain a bit what all the above stand for syntactically, i.e. what
pieces are together and what they represent? I am personally not too
familiar with the uses of @.

I would suggest using the "Edit Configuration File" command, and
case for you, or do you really want to use esc for completion,
instead of the "insert command based..." command?
