type KeyEvent struct {
    AltKey bool

    TimeStamp uint64

Member Type Description
AltKey bool true if the alt key was down when the event was fired, false otherwise
Code KeyCode String that identifies the physical key being pressed. The value is not affected by the current keyboard layout or modifier state, so a particular key will always return the same value.
CtrlKey bool true if the control key was down when the event was fired. false otherwise.
Key string Key value of the key represented by the event. If the value has a printed representation, this attribute's value is the same as the char property. Otherwise, it's one of the key value strings specified in Key values. If the key can't be identified, its value is the string "Unidentified".
MetaKey bool true if the meta key was down when the event was fired. false otherwise.
Repeat bool true if a key has been depressed long enough to trigger key repetition, otherwise false.
ShiftKey bool true if the shift key was down when the event was fired. false otherwise.
TimeStamp uint64 Time at which the event was created (in milliseconds). This value is time since epoch—but in reality, browsers' definitions vary. 
func GetKeyDownListeners(view View, subviewID ...string) []func(View, KeyEvent)

Returns the "key-down-event" listener list. If there are no listeners then the empty list is returned. If the second argument (subviewID) is not specified or is an empty string then a value from the first argument (view) is returned

func GetKeyUpListeners(view View, subviewID ...string) []func(View, KeyEvent)

Returns the "key-up-event" listener list. If there are no listeners then the empty list is returned. If the second argument (subviewID) is not specified or is an empty string then a value from the first argument (view) is returned
