RE: Re: Re: X-FrontEnd crashes upon certain keystrokes
You can prevent control characters from being typed as legal characters by modifying the X front end's resource file. Go to the FrontEnd directory and look for a file called "XMathematica". Look for a set of lines in it that read: *Notebook.translations: #override \n\ <Btn1Up>: selection-put() \n\ <Btn2Down>: selection-get() Change these lines to read: *Notebook.translations: #override \n\ <Btn1Up>: selection-put() \n\ <Btn2Down>: selection-get() \n\ Ctrl<Key>a: \n\ Ctrl<Key>b: \n\ Ctrl<Key>c: \n\ : Ctrl<Key>x: \n\ Ctrl<Key>y: \n\ Ctrl<Key>z Of course, where the colon is, you should continue typing in the Ctrl<Key> sequence for each alphabetical character. This doesn't fix any problems with notebooks that currently have control characters embedded in them, but it does prevent you from adding control characters (accidentally or otherwise) to your notebooks in the future.

I've run into a different bug in the sgi/x front end. Various control characters accidentally typed ( ^x say ) do not crash, or show up on the screen display - but they do get sent to the kernal resulting in the most bizarre errors. I spent a whole day debugging a simple notebook...finally a save-as-text showed these unintentional control codes burried in the input..sigh.
