Go to developer help > autolisp reference > autolisp functions > A functions > first one in list is abs

Hit F1 in editor, or look for developer help in standard help menu

for info on snapstyl, type sysvdlg, place cursor in list and hit s, scroll to snapstyl to read about the system variable that he changed
