250+ Keyframes? How to add keyframes? How can I increase the amount of keyframes on the dope sheet? I'm animating the rigify add-on and it won't let the green line go past 250(it just restarts). Also the keyframes after 250 are light grey as opposed to the ones before 250 that are darker.

thanks
Press the LMB while hovering the cursor over the End window of a Timeline bar and define the number of frames. 


You may also change the start and end frames hovering the cursor over Timeline and pressing S for start and E for the end frame of the animation.
