That’s the same pattern of numbers you’ll find on the keyboard of any calculator or adding machine.

When the HX-20 is in numeric mode, you cannot type any let- ters. (Go ahead. Press the q key. See? Nothing happens. In this mode, all letter keys are disabled.)

The number keys in the top row of the keyboard will also work- although presumably you put the HX-20 into numeric mode because you’d rather not use those keys. However, the numeric keys will not function if pressed in conjunction with alkey.

The following keys work normally when the HX-20 is in numeric mode:

If you don’t press a m key, the following keys will generate the indicated characters when the HX-20 is in numeric mode:

The above keys will not function if used in conjunction with a SHIFT key.

When you want to take the HX-20 out of numeric mode, just press the q key or the 191 key. If you press the q key, you will put the HX-20 into upper case mode. But if you end numeric mode by pressing q , you’ll put the HX-20 into lower case mode. Figure 5-1 summarizes the ways in which you may change screen editor modes.
