It is very easy to exit to Termina Field as Deku, even during first cycle, by backwalking past the East Clock Town guard. The angle must be roughly parallel with the wall but is not precise.
This gainer is useful at in-game times when the lower door to the inn is closed. Using the Deku flower instead is easier but slightly slower. The position needed is a little precise but can easily be found using the black line shown in the video.
Hitting the hidden owl statue activates Index Warp. There are several methods of doing so that are used in speedruns. The main obstacle to reaching it is that being above the load zone in front of the hidden owl at any point will put Link in South Clock Town. The hidden owl statue will only count as being activated if it is on screen for the animation where it opens its wings.
Get ISG and target the wall next to the load zone. Do 1 bomb hover followed by 10 chu hovers to get just above and behind the opposite wall. Hold sidehop right and jumpslash once Link crosses the vertical line on the wall. Hit the owl statue and void, keeping it on screen.
Target the wall, get ISG, and hover with the bomb and 9 chus. Bend a megaflip right (hold left) to reach the hidden owl.
If you fail to unlock the camera on the 6th chu hover, you can unlock it on the 7th chu hover, then proceed as normal, except that you'll need to only curve the megaflip near the end of its trajectory to avoid the load zone.
Get action swap and light the deku stick using the torch. Roll to the SCT load zone, then line up and hit the hidden owl with the long deku stick. Fully watch the animation of the owl statue activating before leaving, otherwise the owl won't actually activate. Although the torch is only lit at night, this can also be done in the daytime by using action swap to fire a lit arrow at the torch, then getting action swap again to perform the trick as shown.
After hitting the hidden owl, it is often useful to store a song to be used later.
Sidehop off the platform, and pull a bomb and shield drop it very early in the sidehop so that the bomb falls at Link's level. Hold shield until the bomb explodes and makes Link hover. Hold up-right and mash the ocarina button to get an ocarina dive, then play the song you want to store quickly before voiding.
This recoil flip skips the guard's textboxes, which is important for speedruns that have a stored song when exiting West Clock Town.
Earning the Adult's Wallet by having 200r in the bank while you have collection delay prevents the banker from issuing the text that normally follows Link getting the wallet. Without this text, the game does not recognize that Link has received the reward. Getting up to 200r in the bank again (withdrawing and then depositing 1r works) after playing Song of Time or activating stored Song of Time will result in the banker giving Link the Giant's Wallet.

This clip can get Link into the Curiosity Shop at any time of any day. Get ISG, hookshot clip through the wall, then immediately shield a bombchu to hover. Sidehop hover twice and then sidehop into the load zone. Move the control stick down during the sidehops to bend them backwards towards the door.
By using c-up through the wall, it is possible to target Kafei and talk to him without ascending the stairs.
The key is to walk a bit to space your last roll properly to catch the bombers without them running away.
This video is for an intermediate strat. The risky strat is ~4s faster than this, and the safe strat is ~3s slower than this.
See 16:50.
Drop a bomb on the platform, then transform goron. Curl up and roll slightly into the door to prevent Link from rolling down the small slope. Time a goron bomb boost for maximum height.
