The same occurs with webkit-gtk-1.1.11 under linux

I confirmed Gtk WebKit2 on r142157 don't save undoStack since this uses EmptyEditorClient.
Must using EditorClient in WebKit1 or creating new EditorClient for WebKit2.

Now I just implement CoreIPC messages to send command. I'll do remains soon.
If there is something wrong, please comment.

So we already have webkit_web_view_can_execute_editing_command, which looks like it encompasses all of these. Or am I mistaken?

You're right. There already exists function to do.
But I think the function name is webkit_web_view_execute_editing_command, instead of webkit_web_view_can_execute_editing_command

I confirmed that clipboard command messages are sent properly. Fix to bind only undo and redo signals.

Hrm. So is the issue that Ctrl+Z isn't causing undo to happen? I wonder if this should be hooked in at a different place. Check out webkit_web_view_real_undo from WebKit1. Do we need something like that?
