Hello, If i rightclick on a keyframe i get a menu with the words 'Linair' and In & Out. What does this mean. it seems magix forgot to give information about this..

Also i saw a tutorial back ago that i don't find anymore for dynamic slowmotion.(speedramp). They showed how you could make from 1 keyframe with a click a pair of keyframes... Also don't find information of that anymore... Thanks magix ;-)
