If you mean jumping back and forward through the cursor position history, then in Sublime Text 3 it’s built in via the GoTo menu or keyboard shortcuts:
Jump Back and Jump Forward – Jump Back allows you to go to previous
editing positions. This goes hand in hand with Goto Definition: you
can now inspect a symbol definition, and quickly jump back to where
you were previously. Jump Back is bound to Alt+Minus by default.
The menu entry is Goto > Jump Back
There are plugins available for ST2, for example navigationHistory.
