# basic usage
`:set spell` to open, `:set nospell` to disable, `:set spell!` to toggle.
`]s` and `[s` to go to next and previous spell error. `z=` to see suggestions, but it’s not good. use `:nnoremap \s ea
Use `set spell` to check spellings in vim, if you find word marked wrongly, simple press `zg` to add it the dictionary and `zw` to remove it from the dictionary, they can be revoked with `zug` and `zuw`.
Use `]s` to go forward in the highlighted errors and `[s` to go backwards.
Use `z=` to bring up suggestions
 Vim cast on spell check
zg Add word under the cursor as a good word to the first
name in 'spellfile'. A count may precede the command
to indicate the entry in 'spellfile' to be used. A
count of two uses the second entry.
In Visual mode the selected characters are added as a
word (including white space!).
When the cursor is on text that is marked as badly
spelled then the marked text is used.
Otherwise the word under the cursor, separated by
non-word characters, is used.
If the word is explicitly marked as bad word in
another spell file the result is unpredictable.
zG Like "zg" but add the word to the internal word list
zw Like "zg" but mark the word as a wrong (bad) word.
If the word already appears in 'spellfile' it is
turned into a comment line. See |spellfile-cleanup|
for getting rid of those.
zW Like "zw" but add the word to the internal word list
zug Undo |zw| and |zg|, remove the word from the entry in
'spellfile'. Count used as with |zg|.
zuG Undo |zW| and |zG|, remove the word from the internal
word list. Count used as with |zg|.
