Hi everybody,
you have an idea how I can install more languages? I want my spell
checking to check three languages and not underlining everything to me
that is not English :P
Usually the first thing is to install the appropriate aspell package. For example -
yum install aspell-es aspell-fr aspell-pt
What happens then is up to application.
In AbiWord, for example - you choose the language for the document (or section of document) from the Tools menu.
