Unbind enter key on a mac

Do any of you guys know how to unbind the enter key on a mac? Riot support was really cool and sent me a link to http://www.hammerspoon.org/ and said that this can do the same thing as the autohotkey thing on a PC.

I'm starting to take a look and its slightly complicated as my only experience with coding is doing some statistics in R. If anyone has done it before and can tell me what to do real quick that'd be dope. Then maybe we can pin that walkthrough somewhere.

If not, once I figure it out I'll post on here for the benefit of future players and Riot support members so they have an additional resource
