Get to the on-line SharePoint SDK with one click (MSDN bookmarklet)
While developing custom SharePoint solutions there is a big chance you need to look into the SharePoint SDK on regular. To keep off continuously surfing to the on-line reference, the SharePoint Team have provided us with the compiled CHM files. I admit that the off-line help files do simplify finding the information on a particular class, method or property. They have however two serious flaws: the content is outdated and there is no community content included in the off-line SDK.
