In 1980, the National Language Authority of Pakistan developed a new keyboard layout for typewriters based on Naskh script. This time the layout was based on the frequency tables and bifurcation (balancing load on typist's fingers) techniques, and the characters relating to other languages were replaced with the numerals. Languages spoken in Punjab and Balochistan could be easily accommodated within the Urdu characters. The new standard keyboard also incorporated special characters of other provincial languages, such as Sindhi and Pushto. In 1963, the newly established Central Language Board in Pakistan standardardised the typewriter keyboard. This underscored an urgent need for a standard form of keyboard adaptable for diverse users. 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 organisations.[ However, differences remained in the order of the keys and the number of characters. These developments helped the keyboard layout to evolve from the typewriters to be compatible with computers, to increase the productivity and textual efficiency of the language, especially through modern electronic media. Modern improvements in Urdu keyboard were pioneered by the National Language Authority (Muqtadra-e-Qaumi Zaban) in Pakistan, which standardised the linguistic aspects such as orthography and lexicography. With time, the variety of layouts introduced in the 1950s for mechanised compositions have reduced to very few that are compatible with the new digital age. Since the first Urdu typewriter was made available in 1911, the layout has gone through various phases of evolution. The Urdu keyboard is any keyboard layout for Urdu computer and typewriter keyboards.
