Move cursor to any direction without targeting any specific element

Is it possible to move the cursor a bit to the right, left, up or down direction without scrolling to specific element or doing a mouse over on a specific element?

There has to be a TestObject so the computer can “see” where to start. Then, how about try:

WebUI.clickOffset(findTestObject('yourTO'), xOffset, yOffset)

and the offsets can be positive or negative.
