notcurses-input reads from stdin and decodes the input to stdout, including synthesized events and mouse
events. To exit, generate EOF (usually Ctrl+'d').
Each event will be printed on a single line. Leading that line is a series of modifier indicators:
• 'A'/'a': Alt was or was not pressed.
• 'C'/'c': Ctrl was or was not pressed.
• 'S'/'s': Shift was or was not pressed.
• 'U'/'u': Super was or was not pressed
• 'M'/'m': Meta was or was not pressed.
• 'H'/'h': Hyper was or was not pressed.
• 'X'/'x': CapsLock was or was not pressed.
• '#'/'.': NumLock was or was not pressed.
• 'L'/'R'/'P'/'u': Key was a release, repeat, press, or of unknown type.
By default, mice events are enabled.
