Commands In the steps and examples, the commands you type are displayed in a special monospaced font.
Arguments and Options In command syntax, command options and arguments are enclosed in < >. (The italicized words within the < > symbols stand for what you will actually type. You don't type the < >.)
lp -d<printer name> <filename> <return>
Using the Mouse When using menus and windows, you will select items with the mouse. Here is the default mapping for a three-button mouse:
The Select button is used to select objects and activate controls. The middle mouse button is configured for either Transfer or Adjust. By default, it is set up for Transfer, which means this button is used to drag or drop list or text items. You use the left mouse button to highlight text, and then you use the middle button to move the text to another window or to reissue a command. The middle button can also be used to move windows around on the screen. The right mouse button, the Menu button, is used to display and choose options from pop-up menus.
Menu Options The names of menus and the options that appear on them are separated by a comma. For example, "Select File, Open" means to pull down the File menu and choose the Open option.
Code Continuation Character When a line of code is too long to fit on one line of a page, it is broken and continued to the next line. The continuation is preceded by a backslash.
