Overriding default Matlab key board short cuts

In developing a gui programmatically using figure (not uifigure), I am running into a problem with applying shortcuts. I am using the figure key press function to apply a Ctrl+W short cut. Unfortunately, the default matlab Ctrl+W shortcut executes instead which closes the figure. Both the figure and window key press functions have been used to no success. Is there a way to apply onlymy short cuts to a figure?

NOTE: the same figure developed through GUIDE does NOT exhibit this behavior. Perhaps GUIDE sets the shortcuts somehow?

Issue can be resolved when removing this shortcut in matlab (Preferences --> Keyboard --> ShortCuts). This is not ideal as reminding every user to apply these changes is burdensome.

You can manage keyboard shortcuts in your preferences. From the Home tab, click Preferences in the Environment section. When the Prefences open, naviagate to MATLAB > Keyboard > Shortcuts.

On my computer, this shortcut appears to be inherited from the Windows default shortcuts, meaning you may need to make this change at your system level and not in your preferences.

Thanks for the response. Unforuntately, I don't think I describe the problem very well. A better example is as follows:

1) Create a figure like so:

fig = figure();

2) Make sure this figure has focus by clicking on it.

3) Next, keypress "Ctrl+W".

The figure closes. I would like to programmatically disable the the default matlab shortcuts so I can apply my own Ctrl+W logic.

Alternatively, I would like to know why GUIDE does not apply the default matlab shortcuts.

I would like to also note that other short cuts that are shared with those found in the default matlab list do not exhibit this behavior.

For example, I have also written logic for Ctrl+R, Ctrl+C, and Ctrl+P shortcuts in the figure key press function. These three can also be found in the default maltab shortcut list. However, their logic is not overwritten by their equivalent default matlab shortcuts.

So, it seems the problem is contained only to Ctrl+W. Or specifically Ctrl+W in gui developed programmatically.

This page discusses how to customize your keyboard shortcuts. I am not aware of a method for modifying this programmatically. Perhaps someone else can provide a better explanation.

For me, Ctrl+w is not a MATLAB-specific shortcut. It is a Windows default set shortcut. I can use it to close a Word document, an Excel file, tabs in my browser, and then ultimately my browser, etc.

[Joe Hendrickson]

So GUIDE does not apply Windows default short cuts? This is ultimately a much larger question as gui developed programmatically or through GUIDE should be identical. But in terms of what default short cuts are applied, they are not

Ctrl+w also closes a guide app for me. How do you create a GUIDE figure that does not close? That could help find a way to get this working for your programmaticaly built app.
