There will be several conventions used in this manual. The mouse on the centOS machines in Wyman has three (3) buttons. If you are using a drive given to you by the JHU ECE Department, you can configure your own controls. The following is some terminology we will use in relation to mouse operations:

• “Click left” - press and release the left mouse button (quickly)
• “Click right” - press and release the right mouse button (quickly)
• “Click middle” - press and release the middle mouse button (quickly)
• “Drag left” - press and hold the left mouse button while moving the mouse.
• “Drag right” - press and hold the right mouse button while moving the mouse.
• “Drag middle” - press and hold the middle mouse button while moving the mouse.
• “<…>” - press the key on the keyboard that corresponds to what is inside the <>’s
• “type whatever” - you should type (verbatim) whatever is in boldfaced print
