How to Create Pre-Set Key-frame Animations

[TheToastur 58]

Mine-Imator has many useful features but a really small but helpful one is the preset key-frame animations. If you right click one key-frame there is a button to make an animation to walk to the next key-frame. 

 

Is there anyway I can create my own? When I'm animating I don't like talking or finding voice overs so I just use nods and shrugs. When I make these nods I have to make 5-10 Frames in between each frame turning the head on each frame. It'll be helpful if I could create my own key-frame to key-frame animations with just a right click. It would save me time so I could create longer animations without getting bored/frustrated.

 

Anybody know how? any help will be valued and appreciated.
