One of the things I like about Windows 7 is the Snap feature. You can drag a window to the left of the screen, and it will be tiled vertically on the left, same as the right of the screen. If you drag a window to the top of the screen it will be maximised.
There is a nice tool called AeroSnap that enables these features on Windows Vista and XP. Amongst the drag-and-drop window features, it also has the following hotkeys.
- WIN + LEFT ARROW – Snap window to left of screen. Unsnap window on right.
- WIN + RIGHT ARROW – Snap window to right of screen. Unsnap window on left.
- WIN + UP ARROW – Maximise current window.
- WIN + DOWN ARROW – Restore maximised window. Minimise window.
