The default browsers in squeak-dev images are OmniBrowser based. In
OmniBrowser, we don't create menus, we install commands. To install a
new command:

- Create a class which inherits from OBCommand
- Implement #isActive, #execute and #label (look at the other subclasses)
- In OBCodeBrowser implement a method whose name starts with 'cmd'
which returns the class you've just created.
- Open a new browser

Hi David,

Damien is right - you'll be much better off writing a command than
messing with #yellowButtonMenu. #yellowButtonMenu is just a hack to
tap into the existing implementations of cut, paste, find etc, and
avoid rewriting all that as commands. If you're creating something
new, subclassing OBCommand is a much better way to go.

I see. This part of Squeak is kind of ugly - hence the hack in
OmniBrowser. Take a look at ParagraphEditor and StringHolder. You'll
need to modify both OB and the "regular" behavior in StringHolder.
