Change Chromebook caps key

[breadstead]

Hi. I just bought a Chromebook for writing. I use a mac the rest of the time, and the Chromebook caps key keeps tripping me up.

I keep hitting the search (magnifying glass) button which is where the caps key is on the mac keyboard.

Can you assign different functions to different keys on Chromebook? I don't want or need that search button and would love to reassign it as caps/caps lock.

Thanks.
