[Pharo-users] Small "code" editor example for improving a GUI

Hi, I would like to create some GUI that would be essentially a text area field plus some buttons. The idea is to support - Font size increasing/decreasing. - Syntaxt highlighting for markup languages. I gave a glimpse to the RubTextAreaExamples yesterday, but if anyone knows a more complete example to start with, that would be really helpful. Cheers, Offray
