Rescale timeline?

I have a 105 second animation, and my timeline uses 105 ticks.
I’m close to finishing the animation but want to move one keyframe to a half-second spot, in between two ticks.

I’d like to rescale the timeline so I’m now using 210 ticks, while respacing all my keyframes accordingly. Is there a way to do this? Or is there another method I that would be better?
