The time interval between slides can be set, and the slides will change automatically, or they can be changed manually by pressing the right mouse button or the space bar. The latter is the better choice when the slide show is used as an illustration for a lecture, because the slides can be changed at exactly the right moment. There are about twenty different screen wipes which make the transition between slides more interesting, and they give a very professional appearance. A good example is my lecture on internal control of cash, a very important topic for all businesses. The presentation consists of six slides using a variety of fonts in various sizes, colors, and fill patterns illustrated with drawings from the figure library.
Internal control requires a separation of duties between custody of cash and accounting for cash.
All cash receipts must be deposited in the bank. All bills must be paid by check. A petty cash fund is required for small expenditures for which checks are impractical. Petty cash expenditures are eventually paid by check when the fund is replenished. I bring the first slide up on my monitor, and when hearing a pre-arranged cue, the director puts it on the studio monitors and the monitors at the television sites.
