 {not available when compiled without the |+quickfix| feature}
 'cscopequickfix' specifies whether to use quickfix window to show cscope
 results.  This is a list of comma-separated values. Each item consists of
-|cscope-find| command (s, g, d, c, t, e, f or i) and flag (+, - or 0).
+|cscope-find| command (s, g, d, c, t, e, f, i or a) and flag (+, - or 0).
 '+' indicates that results must be appended to quickfix window,
 '-' implies previous results clearance, '0' or command absence - don't use
 quickfix.  Search is performed from start until first command occurrence.
 The default value is "" (don't use quickfix anyway).  The following value
 seems to be useful: >
-	:set cscopequickfix=s-,c-,d-,i-,t-,e-
+	:set cscopequickfix=s-,c-,d-,i-,t-,e-,a-
 <
 							*cscopetag* *cst*
 If 'cscopetag' is set, the commands ":tag" and CTRL-] as well as "vim -t"
