Generally, the keyboard is divided into these zones: graphing keys, editing keys, advanced function
keys, and scientific calculator keys.

(t ^-a) displays the shortcut menus, which include templates for fractions, n/d, quick matrix
entry, and some of the functions found on the MATH and VARS menus. When some features are active,
you may also see a shortcut menu in the t b location for special shortcuts available in that
particular feature.
Editing—Editing keys allow you to edit expressions and values.
Advanced—Advanced function keys display menus that access the advanced functions.
Scientific—Scientific calculator keys access the capabilities of a standard scientific calculator.
