[function] in curve mode won't let me graphically edit curves with opt key.

    hi guys,
    Failing to graphically adjust the steepness of the curve using the Option key, for this action will only open the help file for [function]. It's been a while since this problem started (I don't exactly remember when). I've been using different workarounds for some time now but for the thing I am doing right now this feature would actually be very handy.
    Anyone experiencing the same? Or am I missing something obvious here?
