Hi,
try this
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
TextModel new
isCodeCompletionAllowed: false;
menuHolder: [];
openWithSpec
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The second line disabled code completion, and the third disables right-click menu.
Disabling shortcuts may be a little more complex. From what I can tell the underlying morph (PluggableTextMorph) has the text stored in��TextMorphForEditView, which has associated SmalltalkEditor.
For your needs you would need to change it to TextEditor, but I don't see any easy way how to change it.
If you will not be able to find a way, please open an issue (for Pharo5), because I think this should be possible.
Peter
