How do I Expand My User Area or Page to a Larger Key Amount on my Vantage/Vanguard?
Perhaps you or your client/student have become extremely proficient at using a particular overlay (4, 8, 15 or 45-Location). Now you would like to move up to an overlay with more keys on it, yet you don't want to lose the overlay you are already familiar with. The option, Expand a User Area or Page in the CHOOSE OVERLAY MENU allows you to place a smaller overlay into a larger one.
To Expand a User Area or Page
1. Open the CHOOSE OVERLAY MENU in the Toolbox. 
2. Select Expand User Area or Page.
3. Select one of the following options Expand User Area or Page depending on the function you want to do.
Note: If selecting Expand a Page, the Pages you will see to choose from will pull from the User Area you are currently in. If you want a Page from a different Area, you will have to switch to that Area first, then activate Expand a User Area or Page.
4a. If Expand a User Area was chosen, select the user area you want to expand.
In this example, if you currently have your customization in Unity 45 Full and want to increase to the 84 location, you will select Unity 45 Full.
NOTE: Your device will not allow you to select a 84 location overlay to expand!
4b. If Expand a Page was chosen, select a page to expand from the page names shown. You may need to select More Items to find your page located on a different screen.
5. Now select the overlay size you want to expand to. In this example, Unity 45 Full is a 45-location overlay so you can only expand to an 84-location overlay.
6. Now you will see a yellow box confirming you want to expand the user area you selected to the 84 location overlay. Select Yes to continue.
7. You will now receive a yellow box telling you that the Expansion is Complete. Select OK
The next time you go to your Unity 45 Full overlay it should look like the picture below.
Now you will only have to assign the blank keys, not the entire overlay.
IMPORTANT NOTE: After you Expand your User Area, you may want to go to Rename User Area in the Choose Overlay Menu and rename it. The device will not rename your user area to the upgraded overlay size. Example: The name of the file will remain Unity 45 Full even though it was upgraded to the 84 location.
