The Quick capture menu is an option available from the tray menu only. Using the Quick capture otion allows you to "break out" of a capture method for a single capture. The best way to explain it is to use a scenario.
Let's say we are capturing Active Windows in order to capture images for writing a help document. Part way through this process, after we have already captured a dozen or so images, we realize we need to capture and Area. At this point, it really would be inconvenient to have to invoke the Settings dialog, go to the Capture page and select Area, then click on Ok, especially as we would have to go to the Capture page and select Active Window, then click on Ok before we selected the next image in order to reset it back. This is why we came up with the concept of a Quick capture method. In the scenario mentioned above, all the user would have to do would be to go to the tray menu and select Area from the Quick capture sub-menu, as seen in the image above. Once the image had been captured, then settings defined in the Settings dialog would take over again, so no need to reset back.
