Pressing Alt followed by two times a seems to be the shortest and fastest way to me.
(After pressing Alt some letters in Menu gets underlined, use them for more such shortcuts)
Alternative:
You can use following AutoHotkey script to automate with just one Hotkey press.
Install AutoHotkey and save following script as .ahk
file and run it. Then you can use Alt+d to adds it to favourites (no other keypress needed).
