Blender-like NumericInput controls

[kungfooman]

Is your feature request related to a problem? Please describe.
Copying/pasting/defaulting a value is not quickly possible

Describe the solution you'd like
In Blender you can just hover a value and press ctrl+c/ctrl+v/backspace

Proof of Concept

console.clear();
hoveredInput = null; // PCUI element
lastCopy = 0.0;
inputs = [...document.getElementsByTagName("input")];
inputs.forEach(input => {
  input.onmouseleave = function(event) {
    hoveredInput = null;
  }
  input.onmouseenter = function(event) {
    hoveredInput = event.target?.ui;
  }
});
document.onkeydown = function (event) {
  if (hoveredInput) {
    if (event.key == 'Backspace') {
      hoveredInput.value = 0; // Math.random();
      event.preventDefault();
    } else if (event.ctrlKey && event.key == 'c') {
      lastCopy = hoveredInput.value;
      event.preventDefault();
      //console.log("copy value", lastCopy);
    } else if (event.ctrlKey && event.key == 'v') {
      hoveredInput.value = lastCopy;
      //console.log("paste value", lastCopy);
      event.preventDefault();
    }
  }
  //console.log(event);
}

Code is just a PoC, it would require proper integration into at least the NumericInput class and/or wherever it makes sense.
