Best free keyboard tools to remap, customize and enhance your keys

NumPad Transformer will let you arm the NumPad of your keyboard with the ability to trigger frequently used functions, including mouse moves. The program tweaks two more buttons besides those in the NumPad — the ScrollLock and the Pause/Break buttons. ScrollLock becomes a “Copy” button, and Pause/Break becomes a “Paste” button. This way two of the most frequent commands can be performed with a single key press. Division (/) becomes a Tab Browser button (“Ctrl+Tab”.) This will let you use just a single key to browse the open tabs of your browser and of other ‘tabbed’ applications. Multiplication (*) becomes a “Close” button (“Ctrl+F4”), to let you close your tabs, documents, etc., pressing a single key. Addition (+) becomes a “Switcher” button, it will let you activate one by one your (non-minimized) open windows. It is an alternative –and very often the most useful– way to browse open windows, instead of using the Alt+Tab switch. Pressing the Delete key of the NumPad, will let you immediately Shutdown your PC, Restart Windows, Log Off your account, or send your monitor to Sleep! NumPad keys from 7 (top left) to 3 (bottom right) will now move the cursor of your mouse. Pressing the same buttons while holding the Shift key will give temporarily more speed to mouse movement.
