Subject: [PATCH 02/12] perf report/top: Make ENTER consistently bring up menu
Date: Tue, 17 Dec 2019 11:48:18 -0300 [thread overview]
Message-ID: <20191217144828.2460-3-acme@kernel.org> (raw)
In-Reply-To: <20191217144828.2460-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
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.
