Operator actuation of a key generates a coded signal representative of the actuated key, but in the multi-character mode, the normal text recorder function of printing or displaying the character associated with the key is inhibited, and instead, a memory device is accessed which has stored at a location corresponding to the actuated key, a sequence of coded signals representative of a plurality of characters, functions or both. The storage device may include a plurality of sets of stored signal sequences representing a plurality of multi-character sequences, the selection between the different storage sets being effected based on a particular key or key sequence previously actuated. Particular keys suitable for use in a multi-character mode are keys representing numeric characters, symbol graphics, or various punctuation marks. The invention is applicable to text recorders designed for use with English or foreign languages.Other References
