yes -- ]i and [i will list the variable definition rather than jump to
the definition.

yes again -- ` is the marker for the last position of the cursor, so ``
will jump to this position.

another way to do it:

i forgot about vim's jump list.  ^o will jump to the previous line in
the jump list, so if you go to a different place in the code with
gD, gd, [^d or ]^d, then ^o will take you back to the original position.
