From a6e51f9fa9124ad6657e6f1c8df2b1033922e9d7 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 21 Oct 2011 10:58:24 -0200 Subject: [PATCH] perf hists browser: Refuse 'a' hotkey on non symbolic views We don't allocate the histogram data structures for --sort lists without "sym", so, just like was done for the menu, don't try to annotate when 'a' is pressed, just warn the user about it.
