Selection
//wand 		Gives you the "edit wand" (wooden axe, #271) which can be used to mark regions. Left click to set the first position and right click to set the second position.
//pos1 		Sets point 1 of your selection to the block that you are standing in. This will be a free block.
//pos2 		Sets point 2 of your selection to the block that you are standing in. This will be a free block.
//expand 	[direction] num 	Expand the selection region in the direction specified. The direction can be "N", "S", "W", "E", "U" (for up), "D" (for down), or "me" (the direction that you are looking in).
//contract 	[direction] num 	Contracts the selection region in the direction specified. The direction can be "N", "S", "W", "E", "U" (for up), "D" (for down), or "me" (the direction that you are looking in).
//size 		Gets the number of blocks in that region. Air blocks will be counted.
Clipboard ::::: mod +
//copy 		Copies your selection to your clipboard. Note that your position relative to the selection will be saved.
//cut 	[blockID] 	Copies and removes the area. Either air or the specified block ID will be left in the region's place.
//paste 		Pastes your selection to your clipboard relative to the position that you were relative to the original selection.
//pasteair 		See //paste. Also pastes air. Access to this command is automatically given if access is given to //paste.
//rotate 	angle 	Rotate the clipboard around the minimum position.
/clearclipboard 		Clear your clipboard (and save some memory).
History
//undo 		Undoes your last action. Your history is 15 in size.
//redo 		Redoes your last action. Your history is 15 in size.
/clearhistory 		Clear your history (and save some memory).
Region Operations
//stack 	count [direction] 	Repeats/stacks the currently selected region in a direction. The direction can be "N", "S", "W", "E", "U" (for up), "D" (for down), or "me" (the direction that you are looking in).
//stackair 	count [direction] 	See //stack. Also stacks air blocks. Access to this command is automatically given if access is given to //stack.
//move 	distance [direction] [replaceWith] 	Moves the contents of a region (air blocks not included). The direction can be "N", "S", "W", "E", "U" (for up), "D" (for down), or "me" (the direction that you are looking in). By default, air will be used to fill the previous area.
//moveair 	distance [direction] [replaceWith] 	See //move. Air blocks included. Access to this command is automatically given if access is given to //move.
//outline 	blockID 	Draw faces of your region.
//walls 	blockID 	Draw sides/walls of your region.
::::: mod + //replace 	[fromID] toID 	Replace a certain type of block (if fromID is provided) or all non-air blocks (if fromID is not provided) to another block type.
Point Operations
//fill 	blockID radius [depth] 	Fills a hole in the XZ directions (Y is depth / elevation). You can specify a depth (default is 1) to fill below as well, but the algorithm will only fill downwards the depth. It will not recursively look for adjacent air blocks to fill from that position.
//drain 	radius 	Drains lava and water pools immediately next to your feet. The radius is then used to limit how far away the draining routine will go. Pools have to be touching each other for the draining routine to get to pools farther away than 1 unit away from your feet.
//cyl 	blockID radius [height] 	Create a filled cylinder or circle.
//hcyl 	blockID radius [height] 	Create a hollow cylinder or circle.
//sphere 	blockID radius [raised?] 	Create a filled sphere. For the last argument, use true or yes to have the sphere spawn raised (it is lifted up by the radius amount).
//hsphere 	blockID radius [raised?] 	Create a hollow sphere. For the last argument, use true or yes to have the sphere spawn raised (it is lifted up by the radius amount).
/fixwater 	radius 	Levels water and replaces non-stationary water with water. Stand next to the pool(s) that you want to correct.
/removeabove 	[size] [height] 	Remove blocks immediately above you. If a height parameter is not specified, every block above you will be removed.
/removebelow 	[size] [height] 	Remove blocks immediately below you. If a height parameter is not specified, the hole will extend to the void.
/removenear 	replaceID size 	Remove a specific type of block that is near you. The size of the region used is a cuboid.
/forestgen 	[size] 	Make an ugly pine tree forest. The forest will be in a square area. : limit this to mods +
Tools
/unstuck 	  	Sends you up to the next free block if you are inside blocks.
/ascend 	  	Climb up one level.
/descend 	  	Go down one level.
/ceil 	[clearance] 	Climb to the ceiling above you. A block will be placed underneath to support you. The clearance parameter determines how much extra head space should be given.
/thru 		Go through the wall that you are looking at.
/jumpto 		Go to the point that you are looking at.
