Sorry for that. Please replace "@()" with "@(h,e)" in the 3 above statements.

It's normal nothing happens, no callback is defined. Could you add a
callback to both menu items to see which one is triggered.

Now, it looks like accelerators are case-insensitive in ML. But I tempted
to extend that to support SHIFT modifier. That is, if accelerator == 'z',
translate it into CTRL+Z, it accelerator == 'Z', translate into CTRL+SHIFT+Z.

This wouldn't be strictly compatible with Matlab, but this would add more
flexibility to the accelerator system. Any other opinion?
