====== selection actions ======

===== cursor =====
<code>
//cursor

aliases: //cur
</code>
places the cursor item into your inventory, which allows you to set the corners of your selection by left and right clicking on blocks.

===== set selection =====
<code>
//1 <coords>
//2 <coords>
</code>

sets the corners of your selection to ''[[.:argument-types#coords|coords]]''.

===== move selection =====
<code>
//movesel <coords>
</code>

moves your selection by ''[[.:argument-types#coords|coords]]''.

===== grow or shrink selection =====
<code>
//growsel [bound=*1]
</code>

grows/shrinks your selection along its axes to match ''[[.:argument-types#bound|bound]]''.

===== mask selection =====
<code>
//mask [shape]
</code>

masks your selection to fit into a specific shape.

<code>
//mask list
</code>

lists available shapes.

===== display selection =====
<code>
//selection

aliases: //sel
</code>

prints your selection coordinates in chat.

===== set/display volume limit =====

<code>
//limit <int|"no">
</code>

limit the volume of the selected region when performing actions, in blocks. default is 131072. ''%%//%%limit no'' removes the limit.

<code>
//limit
</code>

display the current limit.

====== world & buffer actions ======

===== set & replace =====
<code>
//set [filter] <pattern>

aliases: //replace
</code>

sets the selected region to the ''[[.:argument-types#pattern|pattern]]'', optionally filtered by the ''[[.:argument-types#filter|filter]]''.

===== fill =====
<code>
//fill <filter> <pattern> [bound=*16]
</code>

starting from each block in the selected region, sets all orthogonally adjacent blocks matching the ''[[.:argument-types#filter|filter]]'' to the ''[[.:argument-types#pattern|pattern]]'', recursively. like a bucket fill!

stops after reaching ''[[.:argument-types#bound|bound]]'', even if adjacent blocks match past that point. this is principally to prevent an infinite recursion, but also has some utility. e.g. ''%%//%%fill air water U'' fills an empty pool with water without overflowing out of the top.

===== undo & redo =====
<code>
//undo
//redo
</code>

undoes or redoes any action that modifies blocks in the world.

===== copy & paste =====
<code>
//copy
//paste
</code>
copies and pastes your selection to and from your copy buffer.

===== move =====
<code>
//move <coords>
</code>

moves the selected region by ''[[.:argument-types#coords|coords]]'', replacing the region it previously occupied with air.

===== flip =====
<code>
//flip [axis=^]
</code>

flips the selected region along ''[[.:argument-types#axis|axis]]''.

===== stack =====
<code>
//stack [times=1] [direction=^] [offset]
</code>

duplicates the selected region a number of ''times'', each time offset by its width in the given ''[[.:argument-types#direction|direction]]''.

optionally, you can supply an additional [[.:argument-types#coords|coords]] ''offset'' to be added each iteration. for example,
<code>
//stack 10 ^ ^,^-1,^
</code>
this command generates a downward staircase made of the selected blocks.
