Drag the part of the body you want to move. Let go to create a keyframe (Checkpoint). It will ask you if you want to undo. To undo type y to continue type n or anything else. Then it would ask you for the easing speed. Type in a number that would determine how many seconds it takes for your object takes to reach its desired location. No animations can be saved, so you can screen record it and show it to your friends. (don't forget to comment me)
Tips and Tricks: To avoid having the problem on selecting a body part you can make a tiny bit hanging off. This way you can easily (well not that easily) select it ------------------------------------------------------------------------- To create a delay, click on a body part, then don't move it. When it asks you for your easing speed, just type in how much you want to delay it. ------------------------------------------------------------------------- To undo when it is too late, move the object back to the original position but put the easing speed as 0. (This would nearly immediately teleport it back. ------------------------------------------------------------------------- As rotation does not exist. Try moving it left slightly and then right slightly. This would give a rotational like movement.
