Making Selections with the Mouse

This manual does not give instructions on how to use the mouse in the step-by-step procedures, therefore a summary is provided here.

When the terms select, choose and click are used, it means position the mouse pointer over the on-screen item and click the left mouse button. Sometimes you will be asked to select an item from a menu and then another item from a pulldown menu. In this case, do not release the mouse button after the first selection. Hold down the mouse button and move the pointer to the required selection in the pulldown menu, then release. A series of mouse selections separated by greater than symbols (>) indicates that the selections should be performed in sequence. An example is File > Save As.

If you need to get a readout of values at a particular point on the data trace, put the mouse pointer at this point and click middle to display the x- and y-axis values.

To edit information (such as variable names or values) in software, move the mouse pointer to the information to be edited. Click left with the mouse and move the pointer over the old information to highlight it. Then type in the new information over the old, and press Return. Use the Insert and Delete keys if necessary.

Software Backup

It is important that you make periodic backups of your system disk to guard against accidental loss of data. You can use the script /etc/backup or the tar command to make backups. It is highly recommended that you make a tape backup of the system disk before you begin using the system.
