GitUI\CommandsDialogs\SettingsDialog\Pages\ShellExtensionSettingsPage.Designer.cs，but, how can I bind an event handler to it? sorry that I can't find it.
as illustrated, Lock and UnLock are appended to chlMenuEntries, but weirdly enough, I can't find where to bind an event handlers.
Shell extensions are implemented in a separate project
GitExtensionsShellEx, I'm guessing you'd need to look in there
GitExtensionsShellEx.cpplines around 500ish
