I use trigger phrases where appropriate. Sometimes a single word would be misleading. For instance, with Patricia Seybold's "The Customer Revolution," I had trigger phrases "customer franchise" and "customer capital." In each case, just taking one of the words would have been less precise. I'm sure that she uses "customer", "franchise", and "capital" as single words throughout the book. Only together do the words have a special meaning for her. If I honed in on just "customer", I could be dipping for hours...
