I am looking for a script/tool which allows me to snap graph editor key values to each other. In Maya I have ack snap key values: "Snap all the values of the selected keys to the value of the last selected key.
Haven't heard of a tool that does this. A workaround would be to copy the Y value of the target key, and paste it to the Y values of the other keys (The "key properties" dialog allows multiple keys editing at once)
