Thanks for the reply. In fact, match no= 11 and \11, and tokens greater than 11 all work. It’s only \10 that’s a problem.
Yes, rules for sentences with more than ten tokens are very useful for catching tense shift errors and run-on sentences where two sentences are joined with a coordinator but no punctuation. For example:
Helen and I woke up early this morning but I don’t have time for breakfast.
This sentence has 17 tokens includiing SENT_START. To indicate that the comma should come before the coordinator, you might want to include \9, \10 \11… in the suggestion.
To correct the tense shift error, you need to substitute “didn” for \12.
If there is a better way to reference these tokens, please let me know.
