Is there a way to turn off keyboard shortcuts in Trello?
They break my regular navigation keys.
There is no such option, sorry.
I don't know if Trello has an option for this but you can try tweaking your browser to disallow sites from binding keys. For example, this worked perfectly in my Opera (12.14, Linux): http://my.opera.com/community/forums/topic.dml?id=1083712&t=1363764906&page=1#comment10187842
