Is het mogelijk om een knop in een browser te maken die, als men erop klikt, direct de windows calculator opent? (zonder eerst popup met "openen, oplsaan, ...")
Ziehier het resultaat:

In Opera werkt hij niet echt lekker :) Dat komt voornamelijk omdat de cijfers als sneltoetsen worden gebruikt.
En gewoon typen in het textvakje werkt daar ook niet goed. Alleen als je echt de knoppen gebruikt werkt het lekker.
