Workflow improvements-Swap "Ctrl+backspace" and "Backspace" buttons to reset any value.

when I want to reset a value to zero, like position X, I hover my mouse to location X in Toolshelf and press "Backspace" but it reset Y and Z positions too. I know I can press "Ctrl+Backspace" to reset X only but by default "Backspace" should be used to reset the single value to zero.
