guide.
l Procedures are presented as numbered lists. A single bullet indicates that the procedure
has only one step.
l Bold type is used for the following:
l Keyboard entries that should be typed in their entirety exactly as shown. For example,
“copy file1” means the word copy must be typed, then a space must be typed, and
then file1 must be typed.
l On-screen prompts and messages, names of options and text boxes, and menu com-
mands. Menu commands are often separated by carats. For example, “click HFSS>
Excitations> Assign> Wave Port.”
l Labeled keys on the computer keyboard. For example, “Press Enter” means to press
the key labeled Enter.
l Italic type is used for the following:
l Emphasis.
l The titles of publications.
l Keyboard entries when a name or a variable must be typed in place of the words in ital-

Draw tab and execute the Box command to draw a box.
