Abstract
Graphics display system having a moving cursor, such as a cursor, for selecting a displayed entity with the capability of determining which one of several lower level entities in the vicinity of the cursor is to be selected. The correlation of a cursor with a entity intended to be selected is performed by calculating an index that does not represent the actual distance, which is time consuming, but rather represents a value, more quickly calculated, such that the size order among the indices is the same as the size order of the distances they represent.
