Average need for replacing keyboards is three months... I usually keep an extra handy... but as I work from home often other "borrow" spares. This app has saved my back side a few times until I can replace my keyboard. Only thing I would have added is the directional arrows... or turn off the numeric key pad and use the 2 4 6 8 as arrow keys... just a thought as I use them often.
