Animation play: Follow feature. Enabled from playback menu in the 

timeline.

When enabled, ipo, dopesheet, NLA, timeline, clip and sequence editors
will follow the current frame during animation. When the cursor reaches
the end of the screen, then the next range of frames of the same width
is displayed.
