Slogan tokens are of the form :
[:slogXX_label] for text slogans
[:slimXX_label] for image slogans
XX : represents the index of the slogan token, which is used by Q++ to refer to it in the Slogan Rules. The allowed values are from 1 to 15, and do not have to be consecutive (ie. you can have a slogan token of index 1, another of index 5 and one of index 12 in the same grid).
label : is an identifier available to you to describe each slogan token. Examples would be [:slog01_BiblicalQuotes], [:slog02_LincolnQuotes], … The underscore between the index and the label is optional but helps legibility.
It is important to note that only the index matters to Q++; the label is there for your convenience. Therefore the tokens [:slog01_ListA] and [:slog_ListB] are the same token for Q++, a slogan token of index 1. If you use the same index with different labels, Q++ will issue a warning.
Note that the [:slim] token is one of Q++'s Image Tokens. Make sure you read the section on Image Tokens, below, as these tokens have some important specificities.
