Definition and Usage
The metaKey property returns a Boolean value that indicates whether or not the "META" key was pressed when a
mouse event was triggered.
Not all keyboards have the meta key. It is common for Sun microsystem
keyboards, and MIT and LISP machine keyboards. The meta key is either labeled
"META" or marked with a solid diamond "◆" symbol.
On Mac keyboards, the META key is represented by the the "Command/Cmd" ("⌘")
key.
Note: This property is read-only.
