Historians sometimes assert that any "encoding system" using a fixed value for the change in positions in the alphabet is a (n example of a) Ceasar Cipher -- ie, if the value for the change is +3, A (in position 1) becomes D (position 4). 13 is the oft-cited value.

In the computer world, it's often called ROT13 for rotate 13 positions. moritz' example above provides an example.

I don't know about a "10 shift to the right" -- certainly, as indicated in para 1, that would be a valid way to implementing a Ceasar Cipher... and so would a 10 shift to the left but (IMO) both would make it easier to err if "encoding" manually.

If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post.
