$cons->InputReads an event from the input buffer. Returns a list of values, determined by the type of event. A keyboard event will contain the following values, in order:
Event type (1 for keyboard)
Key state - true if the key is being pressed, false if the key is being released
Repeat count - the number of times the key is being held down
Virtual keycode of the key
Virtual scancode of the key
ASCII code of the character (if the key is a character key, 0 otherwise)
State of the control keys (SHIFTs, CTRLs, ALTs, etc.)
A mouse event will return the following values, in order:
Event type (2 for mouse)
X coordinate (column) of the mouse location
Y coordinate (row) of the mouse location
Button state - the mouse button(s) which are pressed
State of the control keys (SHIFTs, CTRLs, ALTs, etc.)
Event flags for the type of the mouse event
This method will return undef on error.
Note that the events returned depend on the input mode of the console;
for example, mouse events are not intercepted unless ENABLE_MOUSE_INPUT is specified.
