Electronic system with a rollable display and a keyboard that are utilized to imitate a typewriter
An electronic device, method, and computer program product imitate a typewriter. A top horizontal row of a virtual typing sheet is presented on an upper portion of an extendable display. Keystrokes received by a text input device are monitored and corresponding characters are presented across the top horizontal row of virtual typing sheet. In response to a next line transitioning condition (e.g., reaching an end of a current row or detection of a return keystroke received via the text input device), the extendable display is triggered to upwardly extend by an increment corresponding to vertical dimensions of a line spacing and font size of the characters associated with the top horizontal row. Presentation of the virtual typing sheet and the top horizontal row at the corresponding line spacing are upwardly adjusted to insert a new lateral row for presenting keystrokes.
