Keys mapping

Keypress Node supports following sample keys mapping:

up, down, left, right, space, backspace, return, escape, a, b, c, d, ..., 1, 2, 3, ...

If you do not specify input key, all keys will be captured. Insert debug node to see all captured keys mappings.

Shift & ctrl capturing is currently not supported due to inconsistencies in different terminals (TODO).

Note: Keypress capturing works only when terminal window where you started node-red is in the front. If your terminal does not support ttty, you will see keys output in terminal.
