The Bug:

The words "forwards" and "backwards" within two movement key bind strings aren't spelled in American English.

Minecraft's source language, which is English, United States, always spells words in American English, however, the words "forwards" and "backwards" within two movement key bind strings aren't spelled in American English. They should be spelled as "forward" and "backward" instead of "forwards" and "backwards".
