If you find yourself running out of room on your keyboard layout, then add more space by adding additional pages to the layout. You can add as many pages as you need, and quickly switch between different pages.
To add pages to your layout, go into Design Mode, and select Layout Settings. Then enter the number of pages to set how wide your layout is. Also note that there is an option to enable or disable scrolling.
Switching between layout pages is easy. If you have scrolling enabled, just swipe your finger across the screen to move between pages while in Use Mode. If scrolling is disabled, then add a control to your layout and define its action to switch to a different page. To do this, edit your control as normal and go to the tasks screen, press the + button and select Switch To Page. Then select the page you want to switch to when the control is used.
