Ask HN: Word tips?

I use Word a lot from time to time to write big reports and it is quite frustrating. I know Latex is superior and I have started using it for my PhD work. But I still don't know enough to use it in my workplace where I don't always have the time to tinker around.

So, if you use Word to write big documents, do you have any good tips to share? I find that as soon as documents grow beyond a few pages and have lots of tables and figures, Word becomes really slow. Often, the document structure is screwed and I have to re-reference and re-format things a million times.

I'd be really grateful if you could help.

Thanks.
