TRANSITIONS Many presenters sink in the dreaded quicksand of excessive transitions. Rule of thumb: Avoid nearly all of them. Shimmer, sparkle, confetti, twirl, clothesline, swirl, cube, scale, swap, swoosh, fire explosions, and dropping and bouncing sound like 1970s dance moves, but are all real Keynote transitions. And I never use any of them, except for humor and irony.
