How to change the speed of an animation? Okay so after looking around and not finding anything helpful on the matter, I'm going to ask here. Basically what I want to do is speed up my animation of my model walking. Right now it's 39 frames with little adjustments here and there and moving everything manually would risk something jumping out of place.

If anyone is familiar with Windows Movie Maker or most video editing programs, there's an option to increase the speed, thereby changing a 40 second video to 20 seconds in length while doubling the speed.(sorry if I didn't explain that well)

I wanted to know if there was a similar option in Blender to do this in animation. I'm using this model for an upcoming indie game in Unity if that helps. I still consider myself quite new to this, so if screenshots could be included in any helpful answers, it would be greatly appreciated :)

Also due to the model being in an upcoming game, I cannot share or upload it, sorry :(
While adjusting the FPS will make a faster animation, it doesn't help you when you are making a game. In the Dope Sheet, select all of your keyframes, press S and use the mouse to resize the length of your animation.
