11.2 GUI usage

A wheel mouse is convenient for raising and lowering objects within xasy, to expose the object to be moved. If a wheel mouse is not available, mouse Button-2 can be used to repeatedly lower an object instead. When run from the command line, xasy accepts a command line option -x n, which sets the initial magnification to n.

Deconstruction of compound objects (such as arrows) can be prevented by enclosing them within the commands

void begingroup(picture pic=currentpicture);
void endgroup(picture pic=currentpicture);
By default, the elements of a picture or frame will be grouped together on adding them to a picture. However, the elements of a frame added to another frame are not grouped together by default: their elements will be individually deconstructed (see add).
