How to use this user guideThis handbook accompanies the taught sessions for the course. Each section contains a brief overview of a topic for your reference and then one or more exercises.
Exercises are arranged as follows:
• A title and brief overview of the tasks to be carried out;
• A numbered set of tasks, together with a brief description of each;
• A numbered set of detailed steps that will achieve each task.
Some exercises, particularly those within the same section, assume that you have completed earlier exercises. Your teacher will direct you to the location of files that are needed for the exercises. If you have any problems with the text or the exercises, please ask the teacher or one of the demonstrators for help.
This book includes plenty of exercise activities – more than can usually be completed during the hands-on sessions of the course. You should select some to try during the course, while the teacher and demonstrator(s) are around to guide you. Later, you may attend follow-up sessions at ITLP called Computer8, where you can continue work on the exercises, with some support from IT teachers. Other exercises are for you to try on your own, as a reminder or an extension of the work done during the course.
Text conventionsA number of conventions are used to help you to be clear about what you need to do in each step of a task.
• In general, the word press indicates you need to press a key on the keyboard. Click, choose or select refer to using the mouse and clicking on items on the screen. If you have more than one mouse button, click usually refers to the left button unless stated otherwise.
• Names of keys on the keyboard, for example the Enter (or Return) key are shown like this ENTER.
• Multiple key names linked by a + (for example, CTRL+Z) indicate that the first key should be held down while the remaining keys are pressed; all keys can then be released together.
• Words and commands typed in by the user are shown like this.
• Labels and titles on the screen are shown like this.
• Drop-down menu options are indicated by the name of the options separated by an angle bracket, for example File>Print. In this example you need to select the option Print from the File menu. To do this, click with the mouse button on the File menu name; move the cursor to Print; when Print is highlighted, click the mouse button again.
• A button to be clicked will look like this
• The names of software packages are identified like this, and the names of files to be used like this.
