Usually, when writting code (in Emacs, of course), I forget a lot of times how to use a function, or what are their parameters. So frequently I use devhelp-word-at-point, which opens DevHelp and shows the required information.

But even in some cases DevHelp is not enough, as what I actually need is to see examples of use for that function. In these cases, as Victor suggested, Google Code is a good place where to get it. But it’s a pain in the neck to open a browser, go to Google Code and search for the function.

So I’ve written a simple function for emacs, codesearch-word-at-point, that performs like devhelp-word-at-point, but opening a browser with the results of searching in Google Code. Mapping it to a key (I’m currently using F11 for devhelp and F12 for code search) makes my life easier.
