Based on the original Windows Polish Programmers layout
Extended range of chars for direct typing after holding down the right Alt key (Alt Gr) or the keyboard shortcut Alt+Ctrl, i.a. the Polish quotation marks („ ” » « ‚ ’), the section sign (§), the degree symbol (°) etc.
Improved "`" accent key - from now on, just press the key without the Shift key held down in order to type, without holding any key down, any diacritic or other character that is corresponding to its placement in the layout for Alt Gr (except the bullet char)
The tilde char (~) available after pressing the "`" key with the Shift key held down or also after pressing the accent key and then the space bar
The bullet char (•) available after pressing the "`" key with the Alt Gr key held down
The keyboard layout works only on Windows 2000 and newer. Windows operating systems of the 9x family are not supported.
Some of the extra chars are unable to be entered in older, ANSI-based applications. In most cases, a question mark is returned.
