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.
The remaining keys of LIST, MATRIX, MEMORY , NOTEPAD and PROGRAM
have special chapters of their own.
