Adjusting the Settings for Word Prediction.
You can set Word Predictions options so that words are predicted by how recently you have used them or by how frequently you use them.
The WORD PREDICTION MENU is available on most Spelling Keyboards by select the TOOLS key 
and then selecting 
. It is also available by selecting the Toolbox key 
on the front of the case in the Toolbox.
The WORD PREDICTION MENU is for Word Prediction area words only, not the First Letter prediction words.
Select the Toolbox key on the front of the device case.
Select the WORD PREDICTION MENU key 
Word Prediction: On/Off
To use Word Prediction, you must turn it ON. The default for word prediction is OFF.
You can also turn Word Prediction On from most pages in Essence by selecting the WORD PREDICTION key 
Display Recent Words
In the Display Recent Words option, select the number of recently used words that you would like to see on the display. When you begin to spell a word, your device will display the 5 (or whatever number you have selected) most recently used words that begin with the letter(s) you have typed. The rest of the words on the display will be the most frequently used words that begin with the letter(s) you have typed.
If you set the number to “0”, the words that appear in the Word Prediction window will be the words that you use most frequently, but not necessarily the most recently used words.
Use Previous Word
If this is ON, when you select a predicted word, Word Prediction will display the words that are most likely to follow the word you selected. If you see the word you want, you can select it instead of having to type it. If you turn this option OFF no "most likely to follow" words will be predicted.
Suggest Spelling
When this is ON, if you misspell a word, Word Prediction will try to predict the word you meant to spell.
Selection Area
Large/Normal
Predicted words are visible in the area below the regular Text Display Area. You select a word by pressing on it. If this area is too small for easy use, you can set this option to Large. This allows you to select a word by pressing on it in the Word Prediction Area or by pressing on the space above the word in the Text Display Area. Select Normal to return it to the default setting.
Fixed/Persistent
Fixed creates a fixed grid of locations inside the Word Prediction area. Words are spread out over this grid. This means that if you are using Essence with Eyegaze, the locations do not have to be updated each time the word list changes.
Persistent has the same advantages as Fixed, but the grid is there whether or not Word Prediction is active except when you are in a menu. This eliminates the delay when Word Prediction is turned on and off.
Letter Case
You can specify if you want to see the predicted words in UPPER CASE letters or lower case letters.
Color
The words in the Word Prediction window can be highlighted in any color. The background area can be a different color. Activate the Highlight Color option to select the background color and the text color that you want to use.
In the Text/Background option, select Background Color box or Text Color box. Select a color area in the large box and then use the color bar and arrows to the left of the screen. The very top of the color bar is always white and the very bottom of it is always black. You can touch areas of the large color chart to change colors and then move the arrows to select a color. The four arrows to the right of the screen move the cursor on the color chart in increments of five. Hue, Saturation and Luminosity can be controlled through these four arrows or with the arrows that come with each option.
If you create a color that you want to save, select the Save New Custom Color key. Then select one of the Custom Color keys to store it under. If you select a Custom Color key where you have already stored a color, the new color will take the place of the older color.
Computer Command for “Delete”
You will only use this option if you are using a computer emulation program that has a command for delete that is different from your device’s default command. The default “delete” command is: ßbackspace.
If the delete command for your computer is different you must activate the Computer command for delete option and type in the keyboard emulation command that your program uses. Activate OK when you have finished typing.
When Word Prediction is On and Output is set to Immediate in the OUTPUT MENU, any characters you type are sent to the display and to the computer monitor. When you select a word from the Word Prediction window, the characters that you spelled are deleted from your device display and are replaced by the word that you want. These spelled characters must also be deleted from your computer display. Your device sends the Delete command for each character that is to be erased from your computer, so it is important that it knows the correct command.
NOTE: The computer delete command must be used to delete one character at a time. Delete Word will not work correctly.
Increase a Word's Frequency Value
Word Prediction also keeps track of how often a word is used. The more a word is used, the closer it gets to the front of the predicted words line. If you have a word you use lot and you don't want to wait for it to appear at the front of the line use this option to tell Word Prediction to move it to the front now.
Add a Word
This option allows you to add words to the dictionary.
Select Add a Word and type in the word you want to add.
Select OK.
The word is added.
Delete a Word
This allows you to delete a word from the dictionary.
Activate Delete a Word. Type in the word you want to delete.
You see the word in the Word Prediction Window.
Select the OK key. The word is deleted.
Reviewing Words in the Dictionary
You can review words in the dictionary. Perhaps you want to check out the words that begin with specific letters or maybe you just want to see the whole dictionary. You can review the dictionary by viewing it on your display screen, by seeing it on the display and also hearing it spoken, or by seeing it on a computer monitor or printing it out.
STEP or AUTO are options for how you can go through the pages of words. STEP means that you must activate a switch or touch the screen to move from page to page. AUTO means that your device will automatically change pages for you after the pre-set amount of “looking” time has passed.
NOTE: You can activate the Previous Items, More Items or the Cancel keys at any time whether you are using Step or Auto.
Review to Display
This sends the dictionary to the display screen. When you select this option your device tells you to enter the start letters of the words you want to review. If you want to review all the words that begin with a certain letter(s), just type that letter and activate OK. If you want to see more specific words, type in more letters. For example, if you type in “chu” you will see all the words that begin with “chu”.
If you want to look at the entire dictionary, do not type in anything. Just activate OK.
Review to Display and Speaker
This works the same way as Review to Display except that your device will speak the entries on each page.
Review to Output Method
This allows you to save the dictionary review to a computer using a USB drive or the PRC Bluetooth adapter or to print it out on an IrDA printer. Remember to set the correct options in the OUTPUT MENU (see page Error! Bookmark not defined.).
