QSELECT TYPE <type>       — select all entities of given type (e.g. LINE, CIRCLE)
QSELECT LAYER <name>      — select all entities on the given layer
QSELECT COLOR <n|BYLAYER> — select all entities with given color index
QSELECT LINETYPE <name>   — select all entities with given linetype

Deselects current selection and replaces with matched entities.
