title: How can you change effect in Nivo Slider based off of previous or next slide keypress?
body: <p>I want to change the transition effect on Nivo Slider based off of which button was pressed. Any ideas of how to accomplish this? </p>
  
  <p><strong>Update</strong>
  To clarify, I meant the next or prev button, not a button on the keyboard. What I'm looking for is if a person presses the next button, a slideToRight transition effect is called. If a person presses the previous button, a slideToLeft transition effect is called. Then icing on the cake would be if someone presses a specific slide, if it slides the correct direction. I love Nivo Slider, but I feel like these should be default choosable actions.</p>
