sublimetext3 - Sublime text 2/3: How to move cursor along indentation? Mac OS -

i'm trying move cursor along indentation level. "jump next or previous same-indentation-line"-command.

to illustrate: "|" supposed cursor.

def way_too_big_method   |block1     block2       way many things happening...     end   end end 

command: move down along indentation

def way_too_big_method   block1     block2       way many things happening...     end   |end end 

i know can in vim (maybe need plugin) , know use cold folding that, 3 commands (fold, move down, unfold). used textmate years ago , thought alt+up/down might wrong.

do know way that? go plugin if it's sublime 3 compatible (it quite easy create well, guess), have feeling must implemented in sublime-core somewhere, right?

thanks idea on one!
