It’s very handy to be able to spell-check your Spanish homework, and OpenOffice lets you do just that. To get it working, first you need to install the Spanish lanaguae dictionaries by running:
sudo apt-get install myspell-es
Then, in your document, just go to Tools > Language and pick Spanish for the line, paragraph, or all text – if you don’t see Spanish as an option, then click “more” and change the default language for the document. Ok?
Bien. Adiós.
