QSELECTLISTVALUES
Determines whether the entire drawing is scanned to identify valid options when using the Quick Select command. When this system variable is turned on, the Quick Select command may require additional time when working with very large drawings. If you already know the options to specify, try turning this system variable off to increase performance. When turned off (set to 0), the drawing is not scanned. When turned on (set to 1), the drawing is scanned to prefill the Quick Select dialog box with valid options.
