Clipboard

Command	Parameter	Description
//copy	[-e] [-m]	Copy the selected region blocks to an imaginary clipboard. It also stores the player's position where it is copied.
//cut	[-e] [-m]	Clear the region blocks and put it in an imaginary clipboard. It also stores the player's position where it is cut.
//paste	[-s] [-a] [-o]	Pastes the region from clipboard based from the player's position where it is cut or copied last time.

"//cut" is like "//copy" but also 'deletes' the region in the process.

The clipboard can also be saved as a schematic file.

Parameters	Description
[-e]	also cut/copy entities such as paintings, armor_stands, mobs, etc.
[-m]	sets a mask ID so only those masked blocks will be pasted. ex: "//copy -m 2,7" will only copy grass_blocks and bedrocks and skip copying other blocks.
[-s]	conveniently selects the region where it was pasted relatively.
[-a]	skips pasting air_blocks to avoid 'unwanted deletion' to nearby objects.
[-o]	re-paste where it was previously copied/cut. ex: If the clipboard is still there, "//paste -o" will restore back the objects in the copied region directly.
