However, with the arrival of the digital age, the layout became inadequate for computerized processing that required software backup to select the shape of the character appropriate to the context, and the ability to store multiple language character sets. The keyboard had 46 keys to type 71 Urdu consonants, vowels, diacritics, and punctuation marks, and 21 key symbols for arithmetic calculations and digits. In 1980, the National Language Authority of Pakistan developed a new keyboard layout for typewriters based on Naskh script. This underscored an urgent need for a standard form of keyboard adaptable for diverse users. However, differences remained in the order of the keys and the number of characters. When Urdu was declared as the national language of the independent Pakistan in 1947, a variety of keyboard designs were quickly brought into the market by various individuals and organizations.
