In my current position, it is necessary to write large amounts of technical documentation. For this, I use a variety of tools to create a "master" document, which then gets uploaded to either a SharePoint repository, or to our Wiki.
To build these documents, I use things like Word, Notepad++, OneNote, Photoshop, CamStudio, and maybe a few others, but those are the highlights. I've been playing with a new idea, and am hoping to get some input from the community about their favorite tools, what they like, and what they don't like. Let your voice be heard!
What do you look for in a documentation tool?
