Show/Hide Feature Keys
Some features are used more or less by certain users. Consequently, it is useful to hide unused features to reduce the clutter on screen.
From Themes&Appearance setting you have the option to show or hide Feature Keys.
You have the option to create your Bell Sounds in this section. To do so, tap the Bell button in the Show/Hide Feature Key List. The bell is used as a signal to notify someone that you require assistance. You can either assign your own unique recording to the bell, or use one of Predictable’s pre-created bell sounds.
