-You will notice some familiar notation on some keys like "TAB" and "ESC".  There are also keys that look just like a Row and Column notation. AC01 (Alpha, row C, position 01) is where the "A" key is on most keyboards. The number in the second row of all the keys is the HID Code.  So when you type that key, in "A"'s case, 0x04 is sent to the OS.  The OS then prints on screen the letter associated with that HID Code. You can silk screen whatever you want on the key cap, when the OS sees HID 0x04 it will print "A".+You will notice some familiar notation on some keys like "TAB" and "ESC".  There are also keys that look just like a Row and Column notation.

-Download and go to page 53 of the [[http://www.usb.org/developers/hidpage/Hut1_12v2.pdf|HID Usage Table]].  It is a pretty long and boring document about HID.  There you will see all of the HID Codes available.  Notice that there are only "Latin" characters commonly found on a US Keyboard.  HID does not specify anything other than what you see in the Usage Name column of that table.  Support for non-English characters is handled at the OS level through your region settings and language tables.+Download and go to page 83 of the [[https://www.usb.org/sites/default/files/hut1_2.pdf|HID Usage Table]].  It is a pretty long and boring document about HID.  There you will see all of the HID Codes available. (The Twiddler only supports the codes found on - 10 Keyboard/Keypad Page (0x07).) The Usage ID is shown in HEX, you need to convert it to DECIMAL in order to use it in Tuner.   Notice that there are only "Latin" characters commonly found on a US Keyboard.  HID does not specify anything other than what you see in the Usage Name column of that table.  Support for non-English characters is handled at the OS level through your region settings and language tables.

-If you would like the Twiddler to print "Ф" find it on the Ukranian keyboard.  Using the notion from above, it is located at position AC01. Map that to the ANSI Keyboard - which is "A".  This tells you to use the letter "A" in your chord.+If you would like the Twiddler to print "?" find it on the Ukranian keyboard.  Using the notion from above, it is located at position AC01. Map that to the ANSI Keyboard - which is "A".  This tells you to use the letter "A" in your chord.
