The DEL and CLEAR keys
Another 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 at the cursor position.

CLEAR
key above

SYMB
view then
CLEAR
will erase the whole set.
