Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
Wikipedia has keystroke combinations that can speed up your work, like Alt+⇧ Shift+F to jump to the search box, Alt+⇧ Shift+E to edit, Alt+⇧ Shift+P to preview, Alt+⇧ Shift+S to publish your edits, and many more. Those are for Windows users. On the Mac OS, press Ctrl instead of Alt.
