Drag Lock

The drag lock feature enables a user to move objects on the screen without having to hold the mouse-click button down. To activate the drag lock feature, the user positions the mouse cursor over the item on the screen they would like to move. Once the user positions the cursor, double right-click to lock onto the item. Once locked, the user can move the item with the trackball. Once the user reaches the desired location, activate either the right- or left-click button one time to release the item.

Connecting an accessibility switch on the left side of BIGtrack Wireless will allow the user to left-click via the accessibility switch. Connecting an accessibility switch on the right side of BIGtrack Wireless will allow the user to right-click via the accessibility switch. Accessibility switches not included.
