2.0 beta2 :iron-a11y-keys-behavior.html:419 Uncaught TypeError: Cannot read property 'length' of undefined
Look like 2.0 beta2 has the same issue mentioned in issue #12
iron-a11y-keys-behavior.html:419 Uncaught TypeError: Cannot read property 'length' of undefined
Line 419 of the last iron-a11y-keys-behavior doesn't seem to match Cannot read property 'length' of undefined so I guess you use an old version and maybe face this issue. Can you show your bower dependencies?
@jamesmgg you triggered this issue before can you reproduce now?
I'm currently not using paper-stepper anymore, so I haven't tested it... All I know is that not using shadow DOM (and using Shady DOM instead) fixes the error.

In my bower.json , im using the below to get the paper-stepper
"paper-stepper": "Zecat/paper-stepper#2.0-beta.3"
