 Of course, you can use @racketmodname[pollen/mode] in any Racket source file, not just @filepath{pollen.rkt}. 
 
-Keep in mind that @racketmodname[pollen/mode] is just a syntactic convenience. It doesn't change any of the underlying semantics of your Racket source file. Your Pollen-mode commands are being translated into Racket commands and compiled along with everything else.
+@bold{Major caveat}: @racketmodname[pollen/mode] only works with Pollen's default command character, namely the lozenge (@litchar{◊}). If you've overridden this command character in your @filepath{pollen.rkt} file, your custom command character will work everywhere @italic{except} in @racketmodname[pollen/mode]. This limitation is necessary to prevent the intractable situation where @filepath{pollen.rkt} relies on @racketmodname[pollen/mode], but @racketmodname[pollen/mode] relies on a config setting in @filepath{pollen.rkt}.

 Another good way to use Pollen-mode commands in Racket is for unit tests with @racketmodname[rackunit]. With @racketmodname[pollen/mode], you can write your unit tests in Pollen mode or Racket mode (or mix them).
