+. Point Selection Mode
The string "_+.:S" is a combination of a number of ssget mode strings, each component of which has a different meaning:
"_" (underscore) allows for variation in language; prefixing mode string operators with an underscore forces
the English version.
"+." This undocumented mode string forces ssget to remain in 'point' mode, similar to setting PICKAUTO to 0.
":S" As stated in the Visual LISP IDE Help Documentation, this mode string forces a single selection, that is,
the user may attempt to select a number of objects only once. When combined with the "+." mode string, this
forces a single object selection.
