How to make the keyboard keys on the computer unable to be used to input the Matlab GUI calculator.

I have made a scientific calculator in the matlab GUI, but I want the keyboard keys on the computer to not be used to input values in the calculator. Can it? if so, how or what does the syntax look like in m files? I need an answer. thank you.

It is not really clear what the difference is between this and https://www.mathworks.com/matlabcentral/answers/718885-syntax-limits-the-input-of-digit-values-on-the-calculator-in-the-matlab-gui?s_tid=srchtitle ?

• you could create one radio button for each different value that you wanted to represent
• you could create one push button for each different value that you wanted to represent
• you could create a listbox that listed each different value that you wanted to represent
• you could create one push button for each different character (digit, decimal, sign, etc.) that you wanted to be permitted, and you would use callbacks to build up the numbers
