Spell checking

By default, spell check will be off. If you want to turn it on, run setlocal spell in the Vim command line (if you want spell check to always be on, add set spell to your .vimrc). After turning spell check on, misspelled words will now be highlighted. To move your cursor to the next misspelled word, enter ]s. To move your cursor to the previous misspelled word, enter [s.

Most likely, the word lists you configure with the spelllang option won’t contain some common words you use, thus causing them to be marked as misspelled. Luckily, you can mitigate this issue by adding these words to your spellfile. Your spellfile is a personal word list you can add words to on the fly. To mark a word as good and add it to your spellfile, move your cursor to the word and enter zg.

Customization

• Incremental search option: :set is? :set is :set nois
• Highlight search option: :set hls? :set hls :nohls :set nohls
• Column number :set nu
