F4 Edit Menu
Press (or click Edit) to open the Edit menu, which contains the options
described below.
Num Lock When Num Lock is on (which it is by default), an icon ( ) appears
in the lower right corner of the screen.
To turn Num Lock on or off, select Num Lock from the Edit menu.

With Num Lock on, you can type only numerals (not letters or punctuation
marks) with the keypad. Multiple presses of a key will not cycle through multiple
characters. (That way you can type “100,” for instance, without having to wait
between zeros.) The single exception is the letter E, which you can always type
by pressing decimal point key (
) twice.
With Num Lock off, the keypad operates in multipress text input mode (see
page 90), allowing you to enter letters and punctuation marks.
It is often unnecessary to turn off Num Lock because commonly used letters and
other symbols can be selected from the Functions menus, and the names of data
sources can be selected from the [Data] menu.
Radians
Select or deselect this option to switch the highlighted calculation to
radians or degrees. See “Degrees/Radians” on page 49.
Clear Expression
This option removes the expression that the cursor is on and
leaves a blank line.
Delete Expression
This option removes the expression that the cursor is on
and shifts up everything below it to fill in the blank line.
Insert Expression
This option shifts the expression that the cursor is on (and
everything below it) down by one line to create a blank line at the cursor location.
Data Properties
Select this option to open the Data Properties dialog box for
the highlighted calculation. See page 69 for more information.
