From e4419b8edb6dead17cbc13a477b953399ee7571c Mon Sep 17 00:00:00 2001 From: David Ahern Date: Wed, 19 Oct 2011 11:37:47 -0600 Subject: [PATCH] perf hists browser: Do not exit on tab key with single event TUI help states for multiple event sessions the TAB/UNTAB keys are used to switch events. For single event sessions (e.g., the default) the tab key currently causes the tui to exit. Change that to do nothing since there is not no second event to switch to.
