What are Pagelets in the ECO2 and How do I Program Them?
Sometimes, when programming special pages into a device, you may find yourself copying a particular page over and over again just to change a few icons on that page. What if you could simply change some keys on a page temporarily and then go back to your original page? In essence, that’s what pagelets do.
It’s easier to understand pagelets by seeing them in action or stepping through an example. Here’s one from WordCore 144.
When you want to use a keyboard that contains a set of general computer function keys, you select the 144 KEYBOARD Page from the Core QUICK HITS then the Spell Activity Key. The 144 KEYBOARD page looks something like this:
Remember, to see the overlay keys and the Windows program at the same time, it’s a good idea to go to Key Mode (or ECO in Unity) where only the top five rows of keys are visible.
These keys were chosen because they represent functions that are used frequently in Windows, but what if you suddenly need to use the number pad? One solution might be to create a second version of this 144 KEYBOARD page and add the number pad over on the top left, then link to that page temporarily.
However, another option is to make a pagelet – a page that contains a small number of keys that can “sit on top” of a parent page. Here’s the actual number pad pagelet:
What you do is program the keys you want to see, then use HIDE KEYS to hide all the blank keys you don’t want to see. When you then link to this pagelet, ONLY the unhidden keys are seen; the hidden keys become transparent and you can “see” through to the underlying parent page keys. Here’s what the 144 KEYBOARD page looks like in Key Mode with the NUMBERS pagelet linked:
Notice how everything else stays the same except for the pagelet keys. The icon that linked to the number pad has now become a CLOSE NUM PAD key. This will close the pagelet.
You may also have noticed two other keys on the bottom row, right-hand side: one with a mouse picture and the other with a menu picture. These are also links to pagelets.
Clicking the “menu” key brings up that top row of menu buttons. And look what happens if you hit the “HIGLIGHT” key right in the middle of the arrows on the top right:
You can now use those keys to highlight things in XP documents or notebooks.
As you can see, each pagelet simply replaces a small number of keys on a parent page. This makes it easier to program page functions.
Linking Pagelets to a Page:
NOTE: You must have both the Page and Pagelets created in order to link them together. If you want to link to a new page, you must first create the page. You can also link to any page that has already been created.
1. Activate Modify Page in the Toolbox.
2. Choose the Page you want to link your pagelet from (our example shows the 144 Keyboard Page), next select the icon you want to use (We chose the Mouse Key), now activate OK.
3. Make sure the Type of Message is set to Computer Speech then select Spell Message, or Define Key Function.
4. Spell any text you want spoken when the key is pressed.
5. Activate Insert Tool 
then Set Pagelet or Set Pagelet Temporary. 
Set Pagelet means you will go to the Pagelet and will remain there until you select the key to take you back to your full page. Set Pagelet Temporary means you will go to the Pagelet for one activation, then return to your full page after a keys is selected.
6. You see a list of Pages. Select the pagelet you want to link to. Most pagelets are named beginning with PL to separate them from regular pages. If you create new pagelets, it is a good idea to follow this rule of thumb.
Your text area will be similiar to the message above with your page name in parentheses.
8. Select OK.
9. Now you can select Change Icon to select a picture, Change Label to add a Label, etc.
10. Select OK when finished and try out your original page and pagelet link.
