Access this window by using the Lists->Issues->Issue By Selected Formats and Tags menu item.
This window will support generating a list of issues filtered by a combination of format and issue tags assigned to the issues. The list generated is the same as the list for Lists->Issues->All Issues, but filtered by the selections made. If no selections are made, the output will simply list ALL issues.
Select any number of formats and or issue tags in the displayed lists. Press the Make List button and the list will show in a new window. Just as with the All Issues list, double clicking on any entry will display that entry in the Issues window.
