By using the appropriate routing, you can skip the Earth Temple room in Sky Keep. When using the Courage Lever RBM it is not necessary to fight Dreadfuse, allowing some route variations. For the puzzle directions below, the direction indicates which block you should move into the blank spot. So R means take the block to the left of the empty spot and move it to the right.

Once the rooms have shifted, proceed through the door. Clear the Skyview Temple room, and perform the Courage Lever RBM there. Make your way through the Lanayru Mining Facility Room to the control panel there.
This puzzle takes 2 moves, as follows:

By calling fi frame perfectly after opening the map chest, it is possible to skip the gate opening cutscene and the other fi text afterwards.
In the first room, you can skip using the Beetle to knock the rope loose by using a precise bow shot.
You can also skip the first rotating vine drum by standing in a specific spot and shooting the Clawshots directly to the second rotating vine drum.
As an additional timesaver, you can also backflip right as you shoot the rope to skip its cutscene.
In the LMF Room, it is possible to hit all six eye targets behind their grating without using the timeshift orb.
For the first target, there are two ways to hit it without the timeshift stone.
By standing in a specific spot next to the gate blocking the puzzle blocks, you can shoot behind the grating covering the eye and hit it. This shot is extremely precise, but saves about 3 seconds over running to the lower level.
After entering the area, run down to the lower level, stand underneath the target, and shoot upwards. This shot is easier than the above but slightly slower.
For the next five targets, by standing in specific locations and shooting at a precise angle, you can hit the eyes' hitboxes before the arrow hits the grating.
Whatever method is used, these shots skip having to use the Gust Bellows and bringing the timeshift orb with you through most of the room.
When you enter the Fire Sanctuary room containing the Triforce of Power, clip though the vine in front of you with Clawshot Vineclip. You will land OoB; run over to the other side of the room and use the clawshot on the vines next to the Triforce symbol to get back inbound.
By combining the uses of Reverse BiTMagic and Faron BiT, it is possible to set the gate blocking the Triforce of Courage to be down. This skips all of the Courage Room fights, and also skips the small key and with it Dreadfuse, and finally also allows a faster puzzle solution for Sky Keep, skipping puzzling once. The flag in question is 3x10, and can be obtained in two places.
The corresponding flag in the Sky is talking to the Bartender after breaking the Chandelier. In this case, you should use BiTMagic to set 3x80 to remove the Lumpy Pumpkin Intro cutscene, and you can also use BiTMagic to set 1x80 to slightly shorten the Chandelier breaking cutscene and 0x01 to shorthen the Bartenders text.
This method is preferred when Faron BiT is set up with the Faron Pillar method (because it allows you to dive to the Lumpy Pumpkin immediately)
The corresponding flag in Faron is pushing the 2nd log in the woods, the one that is next to where you rescue Machi at the beginning of the game. Begin pushing the log off the cliff, then quickly start your file before the cutscene plays, showing the log pushed off the ledge. Then make an environment change and the gate blocking the Triforce of Courage will be raised.
This method is preferred when Faron BiT is set up with the Eldin Pillar method.
It is possible to hit the first bow switch while standing on the dirt patch located in the center of the room.
The strategies for Dreadfuse are exactly the same as those for Scervo in the Sandship; see that page for details. The only difference between the two is that Dreadfuse is shinier and left-handed.
Because Stalmaster operates on a one hit = one damage principle, the strategies here are the same as the strategy for the Stalmaster in Ancient Cistern; see that page for details.
The fastest way to kill the Zombie Bokoblins that spawn is to fight the Stalmaster normally until they close in, then plant a bomb and slash it with your sword, killing the bokoblins while damaging yourself.
A slightly safer and slower method is to place a bomb at the very start of the fight without moving. When the Stalmaster begins to attack, shield bash if necessary and back away, letting the Zombie Bokoblins converge on the bomb; it should explode, killing all the Bokoblins and stunning the Stalmaster. You can then finish phase one in two rounds as usual.
To reset the Sky Keep Puzzle, you can simply leave the dungeon. However, there is a way to reset the puzzle while staying in the dungeon.
Save at any Sky Keep Statue. Perform Back in Time and either BiTSave or BiTWarp using the Bazaar Statue. After reloading your file, kill yourself. You will respawn at the Sky Keep statue you saved at, but with the puzzle reset. Usually this causes you to have to leave the dungeon anyway because most rooms are not linked to another with the puzzle in its initial position.
It's possible in the Cistern Basement room to knock the Iron Moblins into the void by grabbing onto the edge of the platform and boosting into them.
The trick is inconsistent and difficult, so this would be considered segmented or TAS only.
By using Reverse BiTMagic, it is possible to set the shortcut gate in the Skyview room to be open. This skips doing the room normally, and this allows for beating Sky Keep without the whip or gust bellows. The flag in question is 9x40. On Skyloft it corresponds to the five crystal reward conversation with Batreaux.
This RBM is slower than doing the room normally, and should only be used in order to skip whip or gust bellows. It should also not be done in the Skyview room as loading that room without committing the RBM will unset the flag. Thus the RBM should be done at the entrance and committed (for exemple by puzzling a little) before entering the Skyview room.
It is possible to skip the clawshots requirement in the Wisdom Room by using a Long Jump Attack (LJA). You normally need the double clawshots in order to get to the alcove where the triforce of wisdom is, as it is barely too far to reach with a standard jump. To skip the clawshots, push the sentrobe around with a barrel until it gets close to the platform we want to jump too. Make sure the timeshift orb is positionned so that the spike gate doesn't exist. Wait for the sentrobe to spawn sentrobe bombs, and wait for them to clip over the platform you want to get to. Then perform a sidehop, target the sentrobe bomb, and immediately jumpslash in order to perform a LJA. This should allow you to jump far enough to skip the double clawshots.
