No default keyboard shortcut for overwrite mode
There is no longer a default keyboard shortcut for Overwrite mode, and OVR no longer
appears at the bottom right corner of the MATLAB status bar. Previously, the Insert key
by default toggled between Insert and Overwrite modes in the Command Window and in
the MATLAB Editor.
Compatibility Considerations
To enable Overwrite mode, assign a keyboard shortcut to this action. On the Home tab,
in the Environment section, click Preferences > Keyboard > Shortcuts. Search or
scroll to find the action name, Toggle Insert/Overwrite Mode, and assign a keyboard
shortcut. Use this shortcut to toggle between Insert and Overwrite modes.
Support requests using prerelease versions
If you have Internet access, you can submit a technical support request to MathWorks
from MATLAB by selecting Help > Request Support. Previously, this feature was only
available in the final version of each release. Beginning with R2013a, this feature is also
available in the prerelease version.
