html editor

Could you please recommend a 'free' htmal editor.

I write on Note Pad. I like to know if the links are working well
before I post them in a blog or submit an article.

I do not have Office Word in my system. After much search and toil
I have got the Live Writer. Does this Writer thing edit html code ?

I read that an html code editor will show up the errors of omission and commission.

Please help me,
