To edit a key, select it in the keyboard preview. Its properties then appear in the lower area, and every change is shown immediately in the keyboard preview.
Using the selectors at the top you can switch the design and the mode directly, without leaving the key tab.
Under "Layout and colors" you set the height and the width of a key in percent. You can also define a safe typing zone that may differ from the design – this is especially useful for frequently pressed keys such as the space or delete key, where hit rates have proven to be very high. Each key can also have its own key color and its own color for the marked state; with the Extended Design Package you can even use an image as the key color.
Using the action fields you assign a function to each action of a key. Available actions are press, hold, swipe in all eight directions (horizontal, vertical and diagonal), rotate clockwise and counterclockwise, as well as touching the key and lifting the finger inside or outside the key. When you select an action, the function dialog opens; its description can be found here. With the Extended Design Package you can assign several functions to a single action – for example different functions depending on the number of quick key presses (multi-press).
For a hardware keyboard you additionally set the hardware key code here and can block the key's original function.
New keys are added via the plus icon and removed with the trash icon. To move a key or to swap the functions of two keys, you first have to unlock the respective action via the corresponding icon – the locks prevent accidental triggering. You can also select several keys at once and adjust their size, safe typing zone and colors together.
On the "Test" tab you can try out your keyboards. The fields require different input types (text, uppercase text, numeric, password).
