already displaying the rightmost portion of the virtual screen. Now, press the q key and the screen will look like this:

ALL GOOD MEN TO COM- '

The cursor is now in the rightmost location of the virtual screen. Now, press the q key. The screen display changes dramatically:

What happened? An “E” appeared in the virtual screen at the cursor location, and then the cursor advanced to the next location in the virtual screen. Since the cursor was already at the end of one line in the virtual screen, it advanced to the beginning of the next line.

The LCD window then moved automatically, to keep the cursor in view. This changed all the visible text, because the LCD screen was suddenly displaying a completely different portion of the virtual screen.

Logical lines vs. physical lines

When you finish typing “NOW IS THE TIME FOR ALL GOOD MEN TO COME TO THE AID OF THEIR PARTY.” the screen will look like this:

TIME FOR ALL GOOD M

D OF THEIR PARTY. 1

The text you typed occupies all of the first line and most of the second line of the virtual screen. Your cursor moved automatically to the second line of the virtual screen while you were typing, even though you never pressed the m key.

The HX-20 moves the cursor to a new line whenever necessary. You may type one sentence that ends up occupying several lines of the virtual screen-without ever pressing the(lmrawlkey. When this happens, we say that you have typed onelogical line, which happens to occupy several physical lines.

To end one logical line and begin a new one, just press the m key.
