how to trace emacs menu? -

-

is there way see emacs doing when choose action menu?
example i'd see lisp commands executed when click on 

tools --> spell checking --> automatic spell checking

this useful learning include init file enable automatic spell check default. thanks.

menus implemented keymaps, , describe-key handles mouse events in general, can use:

c-hk (select menu item)

in instance see:

<menu-bar> <tools> <spell> <flyspell-mode> runs command flyspell-mode, interactive autoloaded lisp function in `flyspell.el'.  bound <menu-bar> <tools> <spell> <flyspell-mode>.  (flyspell-mode &optional arg)  toggle on-the-fly spell checking (flyspell mode). [...]

actually tracing lisp calls different question (trace-function, built-in elp profiling library, debug-on-entry , 2 debuggers in general useful tools), in case clicking menu item calls function interactively, there's nothing trace :)

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
