Opera

It is possible to select which editor you would like to load to display the source code of documents opened in Opera.

Choose any program in the source viewer field by opening the "Tools" ("Opera" on Mac) menu, then Preferences > Advanced > Programs > Source viewer. Click the "Choose" button to search for the program you wish to use.

Source files are useful for learning how to create your own documents, but take care; some documents do not always follow the current style standards and so are not recommended for copying. You can connect to the World Wide Web Consortium's pages (www.w3.org) to see examples of correct usage.

To view the source of a page, go to the View > Source menu. To view the source of a specific frame in a frames document, right-click in the frame and select Frame > View source from the context menu, or select "View frame source" from the "View" menu to view the source of the active frame.
