Consistency helps reduce the learning curve in web applications. When buttons with similar actions are labelled differently across forms, users can become confused about what each action will do.
For example, Close can be unclear because users may not know whether their changes will be saved. Cancel is clearer when the form closes without saving. Save can also be ambiguous if it is unclear whether the form will stay open or close after saving.
We recommend the web standards of:
✅ Figure: Good example - This form uses the standard button naming standards (and has the Default buttons set!)
Avoid vague labels like OK when a clearer verb is available. Button labels should describe the action and the result, so users know exactly what to expect.
