(Laughter) So when that happens -- this works in Keynote, PowerPoint, it works in every program -- all you do is hit the letter B key, B for blackout, to black out the slide, make everybody look at you, and then when you're ready to go on, you hit B again, and if you're really on a roll, you can hit the W key for "whiteout," and you white out the slide, and then you can hit W again to un-blank it.
(Gelak ketawa) Ini berfungsi dalam  Keynote, PowerPoint. Ia berfungsi dalam semua jenis program. Tekan kekunci 'B', 'B' untuk "blackout",  iaitu menggelapkan slaid, agar para hadirin melihat anda semula. Jika anda bersedia untuk teruskan, tekan 'B' sekali lagi. Anda boleh tekan kekunci 'W'  untuk "whiteout", iaitu memutihkan slaid. Anda boleh tekan 'W' sekali lagi untuk kembali ke slaid anda.
