perf report/top: Allow pressing hotkeys in the options popup menu
When the users presses ENTER in the main 'perf report/top' screen a popup menu is presented, in it some hotkeys are suggested as alternatives to using the menu, or for additional features. At that point the user may try those hotkeys, so allow for that by recording the key used and exiting, the caller then can check for that possibility and process the hotkey. I.e. try pressing ENTER, and then 'k' to exit and zoom into the kernel map, using ESC then zooms out, etc. Reviewed-by: Jiri Olsa <jolsa@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-ujfq3fw44kf6qrtfajl5dcsp@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
