The TouchEvent shiftKey property is a read-only property and used for returning a Boolean value which indicates whether or not the “shift” key was pressed when a touch event was triggered.
The TouchEvent shiftKey property mostly returns false because generally, touch devices do not have a shift key.
Syntax :
event.shiftKey
Return Value: It returns true if the shift key is pressed, else it returns false.

Example: Finding out whether the “shift” key was pressed on the touch screen or not.
