How do I un-nock an arrow?

Solution 1:

Hit the ready key ( R by default ). I do this all the time, since I'm paranoid the noise of firing might adversly affect my sneaking.

Console equivalents are X on the Xbox 360, and on the PS3.

Solution 2:

I can think of two ways that will work without firing your arrow.

  1. Sheath your bow.
  2. Change it to another weapon or spell.

Not sure if there other ways tho :P
