The

DEL

and

CLEAR

keys

The next important key is the DEL key at the top right of the

keyboard. This serves as a backspace key when typing in

formulas or calculations, erasing the last character typed. If you

have used the left/right arrow keys to move around within a line of

typing, then the DEL key will delete the character above the

cursor. The CLEAR key above DEL can be thought of as a kind of ‘super

delete’ key. For example, if pressing DEL would erase one function only in

the SYMB view then CLEAR will erase the whole set.

Calculator Tip

Another use for the DEL key is to restore factory settings.

For example, if you move back into the MODES screen and

change to Degree mode, then pressing the DEL key will

restore the default of Radians. Pressing CLEAR in the

MODES view would restore factory settings to all the

entries. This is particularly useful in the PLOT SETUP

view.

The remaining keys of LIST, MATRIX, MEMORY , NOTEPAD and PROGRAM

have special chapters of their own.
