Action Swap, found by Zas:
https://www.youtube.com/watch?v=uVT21aOA_kIThis glitch uses quick draw to let you swap the action of one item into another. It seems it can really only swap a first-person aiming item with a swingable item (or vice versa, kinda).

Any 1st-person item -> swords/fishing rod (child):
-shoots deku seeds
-makes slingshot noise when firing
Any 1st-person item -> stick (child):
-shoots deku seeds
-projectile is invisible(?)
-shot goes upward at an angle
-makes slingshot noise when firing
Any 1st-person item -> empty bottle (child):
-shoots deku seeds
-makes slingshot noise when firing
Any 1st-person item -> hammer (child):
-shoots deku seeds

Any 1st-person item -> swords/fishing rod (adult):
-shoots arrows
-no sound when firing
Any 1st-person item -> hammer (adult):
-shoots arrows
-bow noise when firing
Any 1st-person item -> stick (adult):
-shoots fire arrow (no magic required!)
-shot goes upward at an angle
-bow sound when firing
Any 1st-person item -> empty bottle (adult):

-projectile sounds like deku seed when it hits a wall (doesn't leave arrow behind)
-no sound when firing
Any swing-able item -> 1st-person item:

SWAP WHILE AIMING EFFECTS:
Any 1st-person item -> any swing-able item
-Link holds the item like the 1st-person item you used
Any 1st-person item -> bombs/chus
-bomb/chu armor (explosive is inside Link's body)
Sling -> rang
-shoots deku seeds
-weird 3rd-person aiming
-makes slingshot noise when firing
SWAP WHILE CHARGING EFFECTS:
Sling/hook/bow -> any swing-able item:
-wasteland ambiance starts playing
Sling/hook/bow -> rang
-wasteland ambiance starts playing
Sling/hook/bow -> bombs/chus
-ground jump/Grab-A
OTHER NOTES:
-all swords, fishing rod, and sold out have the same effects
-need ammo to actually shoot something (it will play wasteland music instead of plucking sound when you try to shoot with 0 ammo)
-crouching, among other things, will cancel the glitch
-deku stick as adult lets you shoot fire without magic, but doesn't seem useful since you need water and you can't aim
-you can ground jump with chus, but again, doesn't seem useful
-if you light the swapped deku stick on fire, its hitbox becomes infinite and it's graphics slowly grows
-if you use the boomerang before drawing the sword you quick drew, when the boomerang comes back, the quick drawn item will look like the boomerang until you pause the game
-the wastleland music is because first-person items make a noise when charging, so wasteland is the equivalent noise for swingable items/rang
-effects are different in MM and oot3d. these games also crash whenever the wasteland sound would happen. both need more testing
-other combinations probably dont have interesting effects, but everything should be double checked
-you can't really aim your shots with this glitch, but you can shoot while backflipping to modify the trajectory
-the deku nut shots dont hurt or stun enemies
-you can use this to shoot the target in lost woods, but can't really aim for the bulls-eye
