By alternating A and B inputs frame perfectly after talking to Midna and selecting the warp option, or using the D-pad to open the map, you can delay the map from coming up until you stop alternating these inputs.
Doing this only requires Master Sword to warp, allowing for some big breaks by not requiring map warping.
By warping with Midna, delaying the map, and triggering Midna in front of the cannon, you can bring up the map after the trigger without the need for map warping. This allows you to skip going to Eldin Gorge in Any% entirely, but requires too many frame-perfectly alternating A and B inputs to be useful outside of a TAS.
By delaying the map with 2 frame perfect A/B presses, you can bring up the map at the same time as triggering the Snowpeak intro cutscene. After selecting a warp, the cutscene will cancel out the warp sequence and give Map Glitch.
