See a map in chat of the chunks around you, and who they are claimed by.
Left-click on an unclaimed chunk to claim it.
Claim the chunk you are currently stood on
Automatically claim any chunk you stand on as you move around. This begins immediately with the chunk you're currently stood on
Claiming large areas of land
NOTE: The following commands do NOT immediately claim the chunks, but instead add them to a 'clipboard' from which you can see which lands cannot be claimed, and which will be claimed - while also allowing you to add/remove extra lands and confirm your claims.
Select the chunks within a specified shape
/k claim square
Select a square with the area of (radius*radius) chunks.
/k claim pos1|pos2
Use the options (either pos1 or pos2) to set two corners, between which everything is selected to be claimed in a rectangular shape.
Select a certain amount of chunks in a straight line in the direction you're facing.
Clipboard and Confirming Claims
/k claim clipboard
View the lands you have selected using the commands found in the claiming large areas of land section.
/k claim complete
Actually claim the land you you have selected previously.
