tabs and spaces

ts tabstop sts softtabstop = allows backspace to delete tabs and indentations, default is just to remove space sw shiftwidth = how many spaces to indent using <> (no)expandtab = converts tabs into spaces

##todo

  • install fugitive
  • git init gitignore template for go?
  • swap brackets {} to ()
  • rename a function (is there vim-go func? install GoRename)
  • use nerdtree or windows to refactor code (is there vim-go func?)
  • how to nav between windows and tabs
  • how to nav through help: ctrl-] to open help, ctrl-o and t to go back and forth
  • how do you toggle (i've seen increment value), there should be a way to either invert i.e. 5 => -5 or true => ffalse

##nerdtree

m, # modify current node
a  # add child node
