There are a number of actions you can take on each report. You can access these by right-clicking the report name in the list of reports. Alternately, once you have run a report, there are buttons across the top of the view to invoke each of these:
Chart: Only present if the report is capable of displaying a chart. Clicking this option toggles between the report and the chart.
Configure: Change the properties of this report. You can customize the report to your liking and save it for future use.
New: Create a new customized report based on the selected report.
Copy: The report output can be copied to the clipboard to paste them in another application, like a spreadsheet, for further analysis.
Export: Reports can be saved in HTML or CSV format.
Delete: Customized reports can be deleted. The default reports that ship with KMyMoney cannot be deleted.
Close: Close the current report.
