Incrementally change value on Ctrl+Click

Actually sometimes on heavy calculation if we drag the value blender starts to slow down and we move mouse far way. we struggle to see change and have to type each value manually to see changes. To overcome this issue any suitable key like Ctrl or Shift can be utilized to click on arrows to change value by factor of 0.1 or 10. If take it another step,Also by holding Ctrl+Shift together the factor may be 0.01 and by holding Ctrl+Shift+Alt as well to make factor of 100.

Incrementing just means to add a value. Clicking the arrow adds a value, that's incremental. What do you want precisely?

Your screenshot says to add the value by 10, issue is the increment value is different across fields. Object location is 0.01, Mapping node's location is 0.1, render noise threshold is 0.03.

Do you want a "bigger" increment? If so, I would use a different shortcut. Blender already uses ⇧ Shift as a slower increment while dragging, so why not ⎈ Ctrl ⇧ Shift as an accelerator while dragging, and use Shit and ⎈ Ctrl ⇧ Shift on value arrow click to multiply the increment value by 0.1 and 10 respectively.
