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).
These buttons have labels in the Tutorial, but not afterwards.
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
