Canon S3: Easy Flash Control

In low light conditions I want to know what shutter speed I can achieve without flash, but also want the flash ready in case I need it. And I want to be able to control whether or not the flash is used without having to press any buttons allowing me to make my choice at the last second. It turns out that with a simple trick I can do all of this.

With the shutter button held down and focussed, the Canon S3 shows the shutter speed in the display. If the flash is raised, then a different shutter speed is shown, typically 1/60. With the shutter still held down, if I depress the pop-up flash just a little with my left hand, two things happen: the flash is turned off, and the shutter speed changes in the display.

So I can be ready on a subject, focussed and about to take a picture, but still easily see the difference in shutter speed between flash and no flash, and remain able to turn the flash on or off for that single image by just poking the flash unit a little.
