Usage: Right-click on a node of that type you want to replace other nodes with.
Left-click (normal usage) on any nodes you want to replace with the type you previously right-clicked on.
SHIFT-Right-click in order to store a new pattern.
Sneak-Right-click (alternatively: aux1-Right-click) in order to store a new pattern.
When in creative mode, the node will just be replaced. Your inventory will not be changed.

-- Version 3.0
-- Changelog:
-- 02.09.2021 * Added a history of stored patterns (not saved over server restart)
-- * Added a menu to select a history entry. It is accessable via AUX1 + left click.
-- * Removed deprecated functions get/set_metadata(..) and renamed metadata to pattern
-- 29.09.2021 * AUX1 key works now same as SNEAK key for storing new pattern (=easier when flying)
-- * The description of the tool now shows which pattern is stored
-- * The description of the stored pattern is more human readable
-- 09.12.2017 * Got rid of outdated minetest.env
-- * Fixed error in protection function.
-- * Fixed minor bugs.
