What are the tools that used in technical documentation?

Following tools are used generally in "Technical Documentation" : a) Excel & Word - for creating most documents.For user docs and most other forms of documentation, I see Excel & MS Word being used most often.
b) Visio - for creating diagrams as well as Wire frames.
c) For development documentation, specifically API docs, tools like Javadoc and Doxygen are used a lot.
Wikis are good too.Wiki (media wiki) for everything from design to end user docs as well as documents detailing our lab setups and who is using what machines.
The end user stuff gets imported into acrobat and gets generated into nice PDF's for technical documentation.

Hi,

 

You can use all MS Office tools plus the Adobe Acrobat.
