All keyboards have BloqNum, BloqCaps and BloqScroll keys. Their functions are well-known by everyone, and also you only have three small LED lights to tell you when they are on or off. But sometimes these lights don´t work, or don´t inform you quick enough or you don´realize. For this you can use NumCapsScroll.
The workings of NumCapsScroll are very clear and concrete: you can see on-screen when these blocking keys are on or off without having to look at the keyboard.
NumCapsScroll appears in the form of an icon in the system tray, with three black stripes, one for each one. These stripes turn green when the key is activated.
