The mouse itself is stationary. This is a trackball mouse. The soul use of this is spinning the ball to move the cursor. I am unsure of any hybrid mice with the features you describe tho it made me wonder myself. You can always keep a regular one plugged in next to it. **Q: Any right handers using it to relieve carpel tunnel and repetitive stress injuries in the right hand (by switching to the left)? If so, feedback??** A: Been using the Logitech m570 on right hand + standard Logitech wireless mouse on left hand for years. It's helped a lot with wrist pain. Finally decided to try this Elecom left handed trackball as it doesn't seem like Logitech has any intention of making a left handed m570. Might get the right handed Elecom eventually as well. **Q: what size batteries does it use ?** A: AA battery × 1 required. **Q: Will this mouse work with windows 10?** A: Yes it works great with Windows 10 still having a problem right scroll wheel 2 move across a row in Excel 2013 worksheet sheet.
