The MMIX Editor Key Bindings

The MMIX editor is implemented using the free scintilla source code editing component. See www.scintilla.org for further details. Therefore the MMIX editor inherits most key bindings from scintilla.

Most of the key bindings are obvious, for example the "Page Down" key will move one page down, and we do not need to list them here. Further, we do not list key bindings here that are very uncommon. The following table lists only the "common unusual" key bindings, that is: key bindings that involve pressing the Shift, Control, or Alt key and are used frequently when editing MMIX source code.
