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. 

Below program illustrates the TouchEvent shiftKey property : 

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