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