Quicken can supply you with a quick-and-dirty report called, cleverly enough, a QuickReport. If you're working with the check register, you can produce a quick report that summarizes things such as the checks written to a particular payee or the transactions assigned to a specific income or expense category.

To produce a QuickReport, first move the cursor to the field you want to summarize in the report. Then click the Report button at the top of the register window. Choose the report you want from the Report menu that drops down.
