You are able to change your keyboard preferences to allow for previewing or completing MATHia workspaces from different devices, such as iPads and tablets.
From a launched workspace select the Preferencesgear icon in the upper left-hand corner.
Select the Keyboard settings in the menu on the left side of the smaller window and choose to use a physical or a virtual keyboard. If you are using an iPad or other tablet, you should choose Virtual Keyboard.
Relaunch the workspace if changes do not immediately occur.
