You will all be familiar with the three buttons at the top of windows which allow you to minimise, maximise, restore and close the application. You may also know about double clicking the title bar to restore and maximise the window. Windows 7 has a few more things you can do with the window you are working on.
If you hold down the Windows Button on your keyboard and press the arrow keys, some interesting things occur. You can use the right and left arrow keys to switch between positions occupying exactly half the monitor. This is really useful if you want to drag files from one folder to another or work on one document while looking at another. This also works if you have a multiple monitor set up on your computer.
Windows + Up or Down will allow you to maximise, restore and minimise; although once you have mimised you will need to get the mouse out (or use Alt + Tab) to get the page back.
You can also get windows to resize themselves by dragging them about. Pick up the title bar with your mouse and drag it to the top of the screen; this will maximise the page, drag it down and it restores. Drag the title bar to the far right or left of the monitor and the window will occupy exactly half the screen.
If you have a window restored on the page (in other words open but not maximised over the whole screen) put the cursor over the top edge of the title bar so the up/down cursor shows and drag it to the top of the monitor. This will make the window fill the whole height of the screen area - extending the bottom of the window at the same time.
There is also the facilty to mimimise all windows apart from the one you are working on by picking up the title bar and shaking it.
All little things but well thought out and in the end quite useful, especially if you have a decent sized monitor or a multi-screen set up.
