the source code here.

While disabled, the main windows is hidden.
To show it just re-click on "Disabled".
If you click on options, you can set text
and background colors. Font(size and style) and transparency
level can be modified too.
Finally you can enable hotkey recognition
in a specified program only. To do it:
1) set the program(default is blender) by
selecting "Set class for class control"
and then click with left mouse button
on the program you want to show hotkey;
2) enable "class control" from tray menu. To
disable "class control" just re-click on it.

N.B.: you can resize the window to view more
hotkeys on the same line
