Find out about key fundamentals for trackpad, touch screen, and keyboard interactions.
Trackpad
Users can use the trackpad to navigate and highlight text. On BlackBerry devices with a touch screen, the trackpad gives
users better control over the cursor or pointer and provides an unobstructed view of the screen.
In most cases, an action occurs when users release the trackpad, not when they click it. However, when users click and
hold the trackpad, the action occurs before users release the trackpad.
Users can perform the following actions with the trackpad:

the item has multiple actions, then this action opens the pop-up
