@kindex signal-event
@item signal-event @var{id}
This command signals an event with user-provided @var{id}. Used to resume
crashing process when attached to it using MS-Windows JIT debugging (AeDebug).
To use it, create or edit the following keys in
@code{HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug} and/or
@code{HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\AeDebug}
(for x86_64 versions):

@code{Debugger} (REG_SZ) --- a command to launch the debugger.
Suggested command is: @code{@var{fully-qualified-path-to-gdb.exe} -ex
"attach %ld" -ex "signal-event %ld" -ex "continue"}.
The first @code{%ld} will be replaced by the process ID of the
crashing process, the second @code{%ld} will be replaced by the ID of
the event that blocks the crashing process, waiting for @value{GDBN}
to attach.
@item
@code{Auto} (REG_SZ) --- either @code{1} or @code{0}. @code{1} will
make the system run debugger specified by the Debugger key
automatically, @code{0} will cause a dialog box with ``OK'' and
``Cancel'' buttons to appear, which allows the user to either
terminate the crashing process (OK) or debug it (Cancel).
