PlIt is a keyboard layout for Windows.
It is based on Polish keyboard layout, with the addition of accented letters for Italian alphabet.
As such, it has some limitation, and in particular Italian letters will be available only in unicode applications.
How to use
Just compile the .klc file from the repository with Microsoft Keyboard Layout Creator (MSKLC).
Alternatively, a compiled setup (made with MSKLC 1.4) is available in the download section.
Once installed, it must also be selected as Input Language; it can safely substitute the standard Polish Programmer keyboard layout.
