If you want to move your windows position more precisely on the desktop, you can use the arrows keys in the keyboard instead of mouse. Do you want to know how?
Here is How
It’s very simple. When the program window you want to move is in foreground, press Alt + Spacebar to open the menu and then press M key in the keyboard.
Now use the arrow keys to move that window around on the desktop. The window will move by 11 pixels in the direction of the arrow key per click.
You can then hit the Enter key to place the window at the new position or hit the Escape key to return the window to its previous location.
