Activity 4 (comma, decimal, double zero key)
The comma and decimal (period) are introduced here because they are used so frequently
with numbers. Press the right middle finger south to enter a comma. Press the right ring
finger south to enter a decimal.
Key each of the five lines. When finished, key them again; try to increase your speed. Use
the comma and decimal point for grouping numbers. For example, 134,489.50 is read one
thirty-four, comma, four eighty-nine, decimal, fifty.

As noted above, the zero key is the most used number and frequently two zeros are seen
together, such as in 100, 200, 300, etc.
Key the next two lines at least three times. Push for speed as you repeat a line.
100, 200, 300, 400, 500, 600, 700, 800, 900, 1,100, 1,200, 1,300, 1,400, 1,500
100.00, 200.00, 300.00, 400.00, 500.00, 600.00, 700.00, 800.00, 900.00
This completes the activities to be used for mastering the numbers. If you do not feel
comfortable keying numbers using the DataHand units, repeat these exercises. Number
mastery enhances keyboard productivity.
