Is there a FAQ for this group?

Since I'm not yet familiar with the genre terminology, what search
terms might I use in a Google search to determine the length of delay
between pressing the shutter button on an AF camera and the time the
picture/flash actually fire.  
I believe this time is used by the camera for auto-focusing or flash
charging.  The "hold it half way down" then shoot doesn't work for me
due to poor muscular control.
