Steps to reproduce:

1. Download and open the attached project 'Simple slider project.zip'.
2. Open the 'My Custom Editor' window (Window > My Custom Editor).
3. Press the 'tab' key to make the slider highlighted.
4. Press the right arrow key to change the value of the slider.

Actual results: The system plays an alert sound effect when changing the slider value with the arrow keys.

Expected results: No sound is played when changing the slider value with the arrow keys.

Another reproduction case (requires numpad):

1. Download and add the attached script 'ToggleButtonAndRadioButtons.cs'.
2. Open the 'Toggle, Button, and Radio Buttons' window (Window > Toggle, Button, and Radio Buttons).
3. Tab through the UI elements and press numpad enter key on them.

Reproducible with versions:

Notes:

• Not reproducible on Windows.
• This impacts accessibility.
• While functionally this method works, it is frustrating to hear this sound every time you modify the slider without a mouse.
• Other UI elements that were not tested may also be affected.
• Does not reproduce with game UI when entering play mode, i.e. only in editor windows.
