/**
* synthesizeKeyboardEvents() synthesizes a set of "keydown",
* "keypress" (only when it's necessary) and "keyup" events in top DOM window
* in current process (and the synthesized events will be retargeted to
* focused window/document/element). I.e, this is currently not dispatched
* via the main process if you call this in a content process. Therefore, in
* the case, some default action handlers which are only in the main process
* will never run. Note that this does not allow to synthesize keyboard
* events if this is called from a keyboard event or composition event
* listener.
*
* @param aKeyValue If you want to synthesize non-printable key
* events, you need to set one of key values
* defined by "UI Events KeyboardEvent key Values".
* You can check our current support values in
* dom/events/KeyNameList.h
* If you want to synthesize printable key events,
* you can set any string value including empty
* string.
* Note that |key| value in aDictionary is always
* ignored.
* @param aDictionary If you want to synthesize simple key press
* without any modifiers, you can omit this.
* Otherwise, specify this with proper values.
* If |code| is omitted or empty string, this
* guesses proper code value in US-English
* keyboard. Otherwise, the value must be empty
* string or known code value defined by "UI Events
* KeyboardEvent code Values". You can check our
* current support values in
* dom/events/PhysicalKeyCodeNameList.h.
* If |keyCode| is omitted or 0, this guesses
* proper keyCode value in US-English keyboard.
* If |location| is omitted or 0, this assumes
* that left modifier key is pressed if aKeyValue
* is one of such modifier keys.
* |key|, |isComposing|, |charCode| and |which|
* are always ignored.
* Modifier states like |shiftKey|, |altKey|,
* |modifierAltGraph|, |modifierCapsLock| and
* |modifierNumLock| are not adjusted for
* aKeyValue. Please specify them manually if
* necessary.
* Note that this API does not allow to dispatch
* known key events with empty |code| value and
* 0 |keyCode| value since it's unsual situation
* especially 0 |keyCode| value with known key.
* Note that when you specify only one of |code|
* and |keyCode| value, the other will be guessed
* from US-English keyboard layout. So, if you
* want to emulate key press with another keyboard
* layout, you should specify both values.
*
* For example:
* // Synthesize "Tab" key events.
* synthesizeKeyboardEvents("Tab");
* // Synthesize Shift + Tab key events.
* synthesizeKeyboardEvents("Tab", { shiftKey: true });
* // Synthesize Control + A key events.
* synthesizeKeyboardEvents("a", { controlKey: true });
* // Synthesize Control + Shift + A key events.
* synthesizeKeyboardEvents("A", { controlKey: true,
* shitKey: true });
* // Synthesize "Enter" key on numpad.
* synthesizeKeyboardEvents("Enter", { code: "NumpadEnter" });
* // Synthesize right "Shift" key.
* synthesizeKeyboardEvents("Shift", { code: "ShiftRight" });
* // Synthesize "1" on numpad.
* synthesizeKeyboardEvents("1", { code: "Numpad1",
* modifierNumLock: true });
* // Synthesize "End" on numpad.
* synthesizeKeyboardEvents("End", { code: "Numpad1" });
* // Synthesize "%" key of US-English keyboard layout.
* synthesizeKeyboardEvents("%", { shiftKey: true });
* // Synthesize "*" key of Japanese keyboard layout.
* synthesizeKeyboardEvents("*", { code: "Quote",
* shiftKey: true,
* keyCode: KeyboardEvent.DOM_VK_COLON });
