Microsoft is bringing a popular Apple iOS feature to Windows 10 that allows you to control your cursor by pressing and holding the spacebar while moving your finger. As your finger moves, so will the cursor one character or line at a time, Microsoft announced in their preview build 20206. While useful for those who use Windows 10 in tablet mode, it will become even more helpful when Windows 10 X is released for mobile devices such as 2-1 laptops and the Surface Neo. Microsoft stated that changing the cursor position using the touch keyboard was a desired feature by many.
