For example, thenstruction"copy filel"means to type the w ordcopy, to type a space. and then to type filelMenu/Command Computer type is also used to display the commands that are needed to perform a specifictask Menu levels are separated by forwardslashes (/) For example, the instructionhoose File/Open"means to choose the Opencommand under the file menuItalicsItalic type is used for emphasis and for thetitles of manuals and other publications. Italictype is also used for key board entries when aname or a variable must be typed in place ofthe words in italics. For example, the instruc-rion“ copy filename” means to type the wordcopy, to type a space, and then to type then amc of a filc. such as filelKeysHelvetica type is used for labeled keys on thecomputer keyboard.

Since GUIare basically visual, the best way to learn to use them is by practicingon your systemMost gui systcms usc a mouseas a poinTing device, with whichyou can select areas on the screenfor command execution andmoving from one program toanother. Your mouse may have 2www.door 3 buttons; Maxwell 3D ignoresthe middle button on 3-buttondelsAnsoft products donot usc this button. You canprogram mouse buttons to work in non-standard ways, as you mightwant to if you are left-handed. For simplicity, the left-hand hutton(under your forefinger if you are right-handed) is called the leftbutton, and the one on far right is the right mouse button. You willprobably find the terms intuitive once you use these buttons a fewtimesPoint and click; Right clickTo choose an item with the mouse, first move it on your desk until thearrow cursor is on that item; you are now pointing" at the item. Next,ress and release the left bu tton thlled"clicking " Point-andclick is the most common action you will make with your mouseally, click" refers to a lefise button clickYou can sometimes use your right mouse button to access or entercommands. In the 3d Modeler for instance, a right mouse buttonclick causes a short menu of commands to appear at the moustcursor. Generally, right click "refers to a right mouse button clickDouble-ClickOccasionally you may want to sclect all of thc text in a box,orperform a special lask(such as indicating the end of drawing a linewhile you are using Maxwell 3D. You can do this efficiently byquickly clicking twice with your left mouse button -a doubleDragging objects; Click and HoldWhen you are drawing in the 3D Modeler, you can often use yourmouse to enter objects and move around the screen. Frequently, youwill click the mouse button and hold it down until the next part of thecommand is reached (the object is oved, the next point is enteredand so forth). If you click and hold on the edge of a w indow, you canposition, or drag, the window on your screen. You can often dragobjects in Maxwell; experiment to see w hat will moveTool BarsTool bars are shortcut methods for entering commands. There is atool bar in the 3d Modeler and most of the setup modules for severalcommand s. To use a tool bar. click the mouse cursor on the buttonyou want to use. Here is an example of a tool bar囗。圖哦良风≌固函MenusWithin each screen of maxwell 3d are areas w hich list subsets ormenus,of commands. You can access a menu by clicking your mouseon the word or button that indicates the menu. The menu is pulleddown, listing the commands available on that menu. (For examplethc New command is availablc on the File mcnu. Usually, thc mcnuwill remain displayed until you choose a command, or click on thedesktop to exit.
