I use ctrl-backspace in MATLAB Editor (MATLAB 2015a) to remove the previous word, but it doesn't work in the command window. I tried changing it in Preferences -> Keyboard -> Shortcuts, but there doesn't seem to be the option to bind it to "Remove Previous Word" in the Command Window. In the attached image, you can see that it is set to work in the MATLAB Editor, but when clicking the down-arrow next to where it says MATLAB Editor, it does not show any other options.
This seems like a very common shortcut used by many Windows programs, and it's strange that it should only be allowed in the editor. If it's actually not allowed, why? Is there a workaround?
