VIM tips

* spelling
:setlocal spell spelllang=en_us / :set nospell
]s move to next misspelled word, [s move to prev. misspelled word
z= suggests correctly spelled words under cursor,
1z= takes the first word from the suggestion list
^Xs does the same in insert mode.
:spellr repeats replacements done with z= for all matches
