Previous & Next Keyframe shortcuts not working

[Pesto]

Hi,
The shortcut key combos for previous and next kf are not working. I went into preferences and changed them and they still don't seem to work. Anyone else have this problem?

Thanks

The default ctrl+alt+arrow keys is working for me in Win7, fwiw. I'll have it on my mac at the office next week, and will try it there.

I just tried it and on my Mac, Cmd+Opt+arrow keys works.

Thanks!
