How To Flutter
In this video uploaded by Trix, he discusses how to do perfect flutters, consecutive flutters and the visual cue that he uses.
Perfect Flutter
Normally, a flutter is done by simply pushing the jump button and holding it until a flutter begins, however, this method does not give you maximum height. What you want to do instead is, release B at the peak of your jump and then, as quickly as possible, repress it to do a perfect flutter. Doing this will allow you to gain a few extra pixels of height. It is a 3 frame window to do a perfect flutter.
They can be used to access several areas that are otherwise too high to reach, such as:
- The area above the !switch in 2-4.
- The last room of the bottom-right room in 4-4 (after you shoot the cloud containing the key).
- Traveling over the stone column in 6-4.
- After obtaining the key in 6-6.
The video demonstrates how a normal flutter does not give you enough height to reach the ledge and then how a perfect flutter allows you to just barely make it with the extra height.
Extended Flutter
An extended flutter is performed by bouncing on an enemy and then holding B and there are a couple ways to get the most height out of an extended flutter:
- Hold B just before bouncing on the enemy to get a big bounce. Not holding B results in a much smaller bounce.
- Release B and manually initiate the flutter around the peak of the bounce, rather than just waiting for an automatic flutter. This is sort of the same idea as the perfect flutter.
- You can also follow the extended flutter up with a manual flutter to gain a bit more height.
Extended flutters are used in many levels to reach otherwise unreachable areas like in 1-1 to skip the beanstalk or in 6-4 to travel over the stone column, skipping the need for a key.
The video demonstrates an extended flutter, followed by a perfect flutter as part of the Warpless route in 6-4.
Sustained Flutter
Flutters can be chained indefinitely so that Yoshi does not lose height throughout consecutive flutters, in fact, a few pixels of height can be gained between flutters by doing perfect flutters. This is used to travel across areas where fluttering is faster, such as the water section in 3-4, the 5-4 platform skip or the 6-4 lava skip.
Lava Skip
Lava skip saves about 3 seconds over riding the log. For some people, it's too risky to do, especially with late game nerves and how little time it saves. If you skipped both mid-rings up to this point, dying means you'll have to replay the entire level resulting in multiple minutes lost. Even if you get the mid-ring just before this room, you'll still lose 23 seconds on the low end and 39 seconds on the high end if you fall in the lava. Doing multiple consecutive flutters over a long period of time takes a lot of practice, but you know the saying, practice makes perfect! 
5-4 Skip
The notorious 5-4 Skip is by far the hardest Trick in the whole game, way harder than the already hard Lava Skip. It can take a very long time to land it even once, but the time it saves is very huge, making it totally worth learning. There are 4 different ways to do the skip. All of them are hard (Half Skip is a lot easier though).
A timing comparison for the skip in Any%:
- No Skip (Use platform): 2:27
- Half Skip (w/ Shy Guy): 1:31 (-56s)
- Half Skip (No Shy Guy): 1:24 (-63s)
- Full Skip (w/ Shy Guy): 1:10 (-77s)
- Full Skip (No Shy Guy): 1:03 (-84s)
Full Skip saves ~60s in 100%, whereas Half Skip would save ~40s.
