To make reviewing faster and easier and mouse-less, WaniKani has some keyboard shortcuts.
Check them out:
F Open item info
Spacebar Display hidden item info
J Play audio (vocab only)
/ Open hiragana IME chart
, Last session data
And if you’d like to be reminded of what these shortcuts are during your lessons, there’s a shortcut shortcut (hohoho) at the bottom right-hand corner of your screen.
