Capital Letters
To make capital letters, you can use the shift stroke. The shift stroke is
made exactly like the other letters in the alphabet. The shift stroke is a
single line from the bottom to top starting the stroke from the bottom.
To make the shift stroke:
1. Using the stylus, make a line starting from the bottom and drawing
upwards.
2. Notice that the display changes to reflect the shift command by
placing an arrow in the lower right corner of the screen. The next
alpha character entered will be capitalized.
Cap Lock
Capital letters can be set to always on just like using a standard Caps
Lock key on a keyboard. To accomplish this function, use the stylus to
make two cap shift marks in a row.
