LaTeX, package documentation look-up
Where can I find the documentation for \usepackage{float}? And in general how do I find package documentations? Usually, I google usepackage{<package>} and hope that the documentation will show up.
First source (as I like it now) is at texdoc.net
Second source is to use texdoc from command prompt:
texdoc float
Syntax: texdoc <package name>
Third, if you are using an editor like WinEdt goto: Help -> LaTeX doc and type the package name. (This basically uses texdoc itself). Or just double click on \usepackage as noted by Holle.
And last, but not least is to type: http://ctan.org/pkg/<packagename> in your browser window to directly go to CTAN.
