" shiftwidth=4  sw              This allows you to use the < and > keys from VIM's visual (marking) mode to block indent/unindent regions
" smarttab      sta             Use the "shiftwidth" setting for inserting <TAB>s instead of the "tabstop" setting, when at the beginning of a line
" expandtab     et              Insert spaces instead of <TAB> character when the <TAB> key is pressed
" softtabstop=4 sts             VIM sees multiple space characters as tabstops, and so <BS> does the right thing and will delete four spaces
" autoindent    ai              When you press RETURN and a new line is created, the indent of the new line will match that of the previous line.
