Persian-QWERTY is a phonetic Persian keyboard layout in which the Persian characters are mapped on their English phonetical pendants in EnglishQWERTY keyboard layout. Since EnglishQWERTY is the standard with every Mac, it allows those who are not familiar with the layout of standard Persian keyboard, to locate Persian characters with more ease. The Persian (X)-kbd is a Keyboard-version of the Standard Persian keyboard layout. The differences are: - Unicode Character 'ZERO WIDTH JOINER': (U+200D) is added and is available under the keys: "shift+grave accent" - the letter is moved from the key "grave accent" which made typing slower to the key "E" - The letter is moved from "E" to shift+F the reason for that is because in Persian is more in use then. So you can type much quicker now then before - All the Accents which are in use in the Persian Language are now available in this kbd.
