Abstract
The electronic controls for a typewriter disclosed herein allow the operator to erase a character using automatic erase capability such as disclosed in U.S. Pat. No. 3,780,846 and at the same time to remove any underscores associated with that character. When an underscore command is entered the memory which stores the code representing the characters typed is caused to be altered in its content to indicate upon the reading of that code segment that the character has been underscored and that the character must be erased along with the underscore. The apparatus accomplishes multiple erase cycles to remove the underscore and then the character. In proportional space mode of operation it is possible that multiple underscore erase cycles will be necessary to remove an underscore which is wider than the underscore type font on the type element.
