From: Arnaldo Carvalho de Melo Date: Wed, 24 Mar 2010 19:40:14 +0000 (-0300) Subject: perf report: Add a popup menu to ask what operation is to be performed X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53c540195724b52422da067a31ef6916d2c70202;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf report: Add a popup menu to ask what operation is to be performed Right now it presents a menu with these options: +------------------------------+ | Annotate CURRENT_SYMBOL_NAME | | Exit | +------------------------------+ If the highlighted (current) symbol is not annotatable only the "Exit" option will appear. Also add a confirmation dialog when ESC is pressed on the top level to avoid exiting the application by pressing one too many ESC key. To get to the menu just press the -> (Right navigation key), to exit just press ESC.
