The Answer Editor for mathematical expressions consists of two parts: a
rectangular field where mathematical expressions are entered (the
entry field) is to the left, and a
keypad made of buttons with mathematical symbols is to
the right (Fig. 4.1).
Mathematical expressions are entered and edited using the buttons of the
Answer Editor keypad, as well as the basic keyboard, the Left and Right
arrow keys, the Tab, Enter, and Backspace keys, and the mouse.

NOTE. Buttons are displayed to correspond with the kind of problem being
solved. The selection is made in such a way as to avoid giving a hint to
the correct answer. Keyboard shortcuts
(Fig. 4.2) work only when the
corresponding button is displayed.

Effect

Right arrow - Tab - Enter - Spacebar

moves the cursor one place to the right (ahead)

Left arrow

moves the cursor one place to the left (back)

Backspace

deletes input immediately preceding (to the left of) the cursor and
