One of the minor features I admire most in the common X11-Window-Manager implementations on Linux is the fact that you can move and resize Windows easily without first moving the mouse to a special location of the particular window: Dragging your mouse while holding Alt+(Left-Mouse-Button) will move the window, holding Alt+(Right-Mouse-Button) will resize the window on its nearest edge.
I always missed this little feature when working on Windows. Today I found a script for AutoHotkey, which is a free (GPL) scripting environment for hotkeys. After installing AutoHotkey, simply download and launch the script by double-clicking it and now you’ll have the same behaviour for window movement and resizing as under KDE. Really cool!
AutoHotkey can do a lot more, unfortunately I have not yet had time to try out more.
