We like our SCADA pages with control pushbuttons to open with no objects selected. This way, if someone presses enter by accident they won't start or stop any equipment.
What we used to do was create a 1x1 pixel momentary button, link it to an Analog [Calc] tag named null which doesn't do anything, then layer the other objects which be clicked on in a way that this momentary button is selected when the page opens. This way, the operator needs to tab over to a button before it can be activated with the enter key.
That used to work in versions 11 & 12.0. It's no longer working in v12.1.
