pressing the L (NeXT menu) key. This key is the third key from the left in
the third row of keys in the keyboard. Press L once more to return to the
main TOOL menu, or press the I key (third key in second row of keys from
the top of the keyboard).
The TOOL menu is described in detain in the next section. At this point we

your calculator.

@CLEAR key (F) activates
function CLEAR, which erases (clears up) the contents of the screen. To see
this function in action, type a number, say
123`, and then press
the F key.

functions. However, SOFT menus are not the only way to access collections
of related functions in the calculator. The alternative way will be referred to
as CHOOSE boxes. To see an example of a choose box, activate the TOOL
menu (press
I), and then press the keystroke combination
‚ã(associated with the 3 key). This will provide the following

the upper right side of the keyboard, right under the E and Fsoft menu
keys. To activate any given function, first, highlight the function name by
