Favorite Tricks/Cheats

By cheat - I think you know what I mean - hacks, tips, tricks, workarounds, crutch, whatever. I know we've all got them. I'm curious what others consider their favorite tricks (unless, understandably, you're not willing to share).

My own off the top of my head:
1. The white flash. There's nothing like a ten frame white solid that starts at 100% opacity and drops to zero to cover a lot of mistakes. I keep coming back to it though I feel bad every time.
2. On a system where your deck can record right off the timeline: Hit record on the deck, then scrub the CTI over the timeline quickly. Digitize the scrubbing back in as a clip and use as an odd/interesting background for transitions. The herky jerky motion of doing it by hand makes it interesting.
3. Online voiceover narration. Depending on budget, the value from a professionally done voiceover - even a few lines of text - often adds value well over what it costs. And most can turn it around by morning.
4. Online stock animations. Chosen wisely, well worth the investment to add value.

Anyone have any they care to share?
