There are two font sizes available via the key, with the default size being large. If you press the key then it will change to . Although there is no apparent change when you are typing in the text, the font will become smaller when it appears in the window. Only uppercase is available in this small font. New sketch pages can be produced by pressing the key. The DRAW menu The key gives access to a slightly enlarged menu of simple drawing tools. The key seen on the far right exits from this menu back to the original one. The tools provided are very primitive compared to a computer drawing or painting program. DOT+ The small cursor (cross) in the middle of the screen can be moved around using the arrow keys. If you press the screen key labeled then a trail will be drawn as you move the cursor. Notice the small dot next to the showing that it is engaged. Pressing the key turns the cursor into an eraser (and automatically disengages as well). Pressing the same key again disengages both keys and leaves the cursor free to move with no effect on the Sketch. LINE Moving the cursor to one end of a proposed line, you can now press the key and move the cursor to the other end of the line. When the line is correctly positioned, press the key (or ). BOX A box is drawn in the same way. Position the cursor at one corner, press the key, move the cursor to the diagonally opposite corner and press . 223
