Title Studio - Jitter Interpolation Mode

Can anyone explain to me how the Jitter interpolation mode affects animation?
I’ve tried setting this for an initial keyframe but the resulting animation appears to be the same as if I’d set the interpolation mode to Linear.
Does anyone have any ideas?
Oh, and while we’re on the subject, what does the interpolation modes ‘Export To Host’ and ‘Reset’ do?
As far as I can tell, ‘Reset’ performs the same function as ‘None’.
