[antlr-interest] "Actions, however, can ask for the hidden channel tokens."

[Martin Probst]

Hi,

the online documentation at:

http://www.antlr.org/wiki/display/ANTLR3/Grammars#Grammars-Lexerrules

Mentions: "Actions, however, can ask for the hidden channel tokens.".

But I cannot find any documentation on _how_ exactly rules can ask for  
the hidden tokens. Any pointers?

Thanks in advance,
Martin
