Let's now see how to create a rst document: for this you'll need to type some text in the editor window of TEXworks. (LA)TEX is not WYSIWYG1 software, so you'll have to type the text and the instructions for formatting it and you'll see the result only after typesetting the text. This looks a little bit dry, but one very quickly gets used to it and it is well worth the e ort.
When one opens the editor, it shows a very sparse interface: a title bar, a menu bar, two small toolbars, a large typing zone (white) and, at the bottom, a status bar. We are in the source/editor window. If you have already typeset the document previously, the resulting .pdf will be shown on the right hand side in the preview window.
The rst toolbar has a button to typeset and an drop-down menu to choose the
format for typesetting (we'll choose pdfLaTeX). Knowing that the keyboard
shortcut for typesetting is CtrlT (Mac OS X: T) and that we almost never
change the format, we could even hide this toolbar. The selection of a
format for compiling can also be changed through the Typeset menu.
The second toolbar provides the standard functions: New document, Open, Save | Undo, Redo | Cut, Copy, Paste | Search, Replace.
Even though they are not looking like real buttons, the widgets in the status bar can be clicked. The widgets showing the current position (line or page, respectively), for example, open a dialog to enter a line or page to jump to when clicked. The other widgets typically open contextual menus where some settings can be changed.
As an example of the use of TEXworks, we will work with LATEX, but any other TEX system is possible. In particular, if you need to use some special fonts2
