From 9218a9132f83d2c08cd23c1fd8e8e9b63b47cb5f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Thu, 12 Dec 2019 10:02:33 -0300 Subject: perf report/top: Make ENTER consistently bring up menu When callchains are present the ENTER key switches from bringing up the menu that offers Annotation, Zoom by DSO, etc to expanding/collapsing one callchain level, causing confusion, fix it by making it consistently bring up the menu and use '+' to expand/collapse one callchain level. Next patch will also add an entry to the menu to allow expanding/collapsing, so that people used to ENTER expanding one callchain level can quickly find it and use it instead.
