Training Handwriting
The handwriting recognizer has a preloaded set of common symbols but in order for the recognizer to work properly you should train handwriting by clicking the second option in the handwriting menu. The tool that opens will allow you to train any of the supported symbols that you want to use in your math expression. Each symbol should have at least 20 samples for the recognizer to be effective.
Steps for training a new character:

- In the Symbol Chooser window, select the symbol that you want to train. If the symbol has an asterisk in front of it, the symbol already has training data and you will be overwriting the existing files. If you want to train lowercase letters simply check the box below the main menu next to 'Use Lower Case for Letters + Greek'. Uncheck the box to return to the uppercase letter selections.
- As soon as you select the symbol you want, click the 'Train Selected Symbol' button.
  (The 'Delete Selected' button will delete all training data for the symbol you have selected in the menu; you should see the asterisk disappear. And the 'Stop Training' button will exit the handwriting training program altogether. )
- The Symbol Chooser window will then close and you should see the Math Handwriting Trainer window. In this window you should write your character once and click the 'Add To Training' button. You should repeat these two steps until you have added 20-30 samples of your character to that symbol's training file.
- If you mess up at any time, you can click 'Clear Screen' rather than 'Add To Training' and redraw your character.
- If you decide you don't want to save any of the data for a symbol and you wish to return to the Symbol Chooser window without changing any files click 'Stop Training This Symbol'.
- When training a symbol, make sure that your samples are all drawn in the same way. You should vary the size and the speed at which you make them, but do not change the number of strokes you use or the basic formation of the symbol.
- If you have added at least 20 symbols to the character's training file you can click 'Save Training' to save all of the training for that character and return to the Symbol Chooser window.
- If you have finished training all of the symbols you wish, click 'Stop Training' and return to the main Math Speak & Write window. Otherwise, you can repeat the previous steps.

Steps for deleting a character:

- In the Symbol Chooser window click the 'Delete Selected' button. This will delete all training data for the symbol you have selected in the menu, and you should see the asterisk disappear.
