6 Getting Started with the TI-84 Plus C Silver Edition
Using the y and ƒ Keys
The secondary function of each key is printed above the key in the same
color as the y key. When you press the y key, the character,
abbreviation, or word printed above the other keys becomes active for
the next keystroke. For example, when you press y and then , the
TEST menu is displayed. This guidebook describes this keystroke
combination as y :.
The flashing cursor changes
to Þ when you press y. The Þ may show in
the cursor location, or in the status bar on the top of the screen.
Many keys also have a third function. These functions are
printed above
the keys in the same color as the ƒ key. The third functions enter
alphabetic characters and special symbols, as well as access SOLVE and
shortcut menus. For example, when you press ƒ and then , the
letter
A is entered. This guidebook describes this keystroke combination
as ƒ [
A].
If you want to enter several alphabetic characters in a row, you can press
y 7 to
lock the alpha key in the On position and avoid having to
press ƒ multiple times. Press ƒ a second time to unlock it.
The flashing cursor changes to Ø when
you press
ƒ, even if you are
accessing a function or a menu. The Ø may show in the cursor location, or
in the status bar on the top of the screen.
