StreamKB

StreamKB is a lightweight Java-based onscreen keyboard that reveals the keys that are being pressed with the aid of a user-defined color. It can be integrated within your presentations to show the viewers the exact keystrokes.

Portable running mode

The utility can be stored on USB flash drives or other portable devices and carried with you. Gaining access to the tool’s features requires only running the executable file. It does not write entries in your Windows registry so you can get rid of it using a simple deletion task.

Simplistic interface

The onscreen keyboard looks clean and easy to work with. You can drag and drop it to the desired position on your desktop. In addition, you can make the keyboard remain on top of other programs.
The virtual keyboard is not resizable but it allows you to choose between a small and big size viewing mode. Pressing any key on the virtual keyboard is not going to bring any results because the application is only able to show the highlighted keys activated with your real keyboard.

A few configuration settings

StreamKB gives you the possibility to make several adjustments to the keyboard, namely alter the background, button, highlighted text, and text color. For each of the aforementioned parameters, the utility offers support for fine-tuning parameters, like hue, saturation, value, transparency, RGB, and CMYK.
We have tested StreamKB on Windows 8.1 Pro and noticed that it executes tasks quickly and without errors. It is not a resource hog so you can keep it running in the background without having to worry that it eats up CPU and memory resources.

Bottom line

All things considered, StreamKB delivers a simplistic approach for helping you work with an onscreen keyboard, and can be handled by beginners and professionals alike.
