hey everyone

I was wondering if it is possible to tell maya that when I have an object/joint selected and there are keys on it's atributes. To jump to any following frame in the timeline and I get keys with exactly the same values as before.
I can of course select the atributes I need in the chanel box and hit key selected. But If I want my character to hold for a couple of frames in a complicated pose it can get really anoying to go through all my joints and their atributes.
Is there something like a hidden button like in after effects? Couldn't dind anything so far.

thanks for any help.
