Moving Windows Windows with Shortcuts
--------------------------------------------------------------------------------------
Moving Windows with Shortcuts ：Cun Nan Bian

Method 1 (Maximized Windows are Ineffective)
1. Switch to the window you need to move using Alt+Tab
2. Press Alt+Space, then press the "M" key
3. Use the arrow keys to move the window

Method 2:
Win+←/→ Move the window to the left half or right half of the screen.

Method 3: (Effective for Multiple Screens)
Win+Shift+ ←/→ Cycle the window to display across multiple screens

Connected to a main and a secondary screen, and the secondary screen is not always on. Some program windows were last closed on the secondary screen, and when opened again, they are not visible on the main screen.
Searched many articles and found this shortcut, which works!
