Avoid control-B is "eaten" I am a heavy EMACS user. On the Mac I get EMACS keybindings in most text fields, and on most websites. However, if I am on a drupal website editing an HTML field, control-b toggles bold. Command-B should toggle bold; control-b should move me back a character. 

Is it possible to fix this, on either my client or on the Drupal server?
This has to do with the CKeditor's javascript library rather than drupal. There are several sites and questions around on how to do this, for example this. I haven't tried this, but my guess is that you need to modify the config.js file that lives in your /sites/all/library/ckeditor folder of your drupal installation.
