Edddy now comes with a box select tool that allows to quickly clear parts of your map as well as limiting the area of effect of drawing operations. While dragging, the scroll wheel can still be used to move the cursor in order to select a three-dimensional space, and modifier keys set the selection mode to replace, add, subtract or intersect.

A separate undo stack keeps track of modifications to the selection. Ctrl+Alt+Z will undo the last change to the selection, and Ctrl+Shift+Alt+Z or Ctrl+Alt+Y will redo the last undone change. When using the Fill tool, holding Alt will fill the entire selection.

Copying and pasting remains to be implemented.
