ing mode, depending on what
function button you press at the
same time.

This is the D200’s hot corner, because it has
a collection of some of the function buttons
you’ll use frequently. They can each have
multiple functions, so you need to keep
your camera’s current mode (playback/
shooting, and so on) in mind when you
attempt to access a specific feature. A more
complete description of each button’s func-
tions appears later in this chapter. The but-
tons include:
✦ Playback. Use this button to enter
the picture review (playback)
mode.
✦ Menu. Use this button to access
the D200’s multilevel menu
system.
