SSOF	Select entities strictly inside a polyline.
RRR	Rotate entities around a base point.
RP2	Rotate view to current UCS system.
FRAMESELECTED	View : Frame selected entity.
AREATOFIELD	Converts a selected area (from a polyline, region, hatch, etc.) into a dynamic field that automatically updates when the geometry changes.
TAREA	Calculate area of selected objects.
TLENS	Compute total length of selected curves.
TBLK	Analyzes the selected block references in the drawing, counts how many instances exist for each block name, and exports the results to the clipboard in a tab-separated list.
