Why am I unable to use Copy (Ctrl+C) and Paste (Ctrl+V) keyboard short-cuts in the text editing mode in MATLAB 7.8 (R2009a) with Windows XP?

I am using MATLAB 7.8 (R2009a) on Windows XP to write my code. However, I am not able to use Ctrl+C, Ctrl+V keyboard short-cuts in the MATLAB editor.

The keyboard short-cuts for Copy (Ctrl+C) and Paste (Ctrl+V) may not work if the "Editor/debugger key bindings" preference is set to "Emacs" instead of "Windows".

In order to check the MATLAB Keyboard preferences n MATLAB 7.8 (R2009a) go to File -- > Preferences --> Keyboard and look for the "Editor/debugger key bindings" options on the "Keyboard Preferences" pane. If the "Editor/debugger key bindings" option is set to "Emacs", the Copy (Ctrl+C) and Paste (Ctrl+V) features will be disabled.  To enable these features, change the "Editor/debugger key bindings" option to "Windows" and click on the "Apply" button in the right bottom corner of the "Preferences" window.

If you are using MATLAB 7.9 (R2009b) - MATLAB 7.14 (R2012a) go to File -> Preferences -> Keyboard -> Shortcuts, or for MATLAB 8.0 (R2012b) - MATLAB 8.2 (R2013b) click the Preferences button in the Environment section of the Home tab and navigate to Keyboard -> Shortcuts.  Make sure that under Active Settings, "Windows Default Set" is selected.  This will ensure that the Keyboard Shortcuts Preferences are mapped to the default Windows settings i.e. Copy (Ctrl+C) and Paste (Ctrl+V).

Note: Make sure that there are no conflicts listed under the 'All Possible Conflicts' section if you included other customization.
