Retarding key presses

[ralfw]

Keys pressed (a-zA-Z0-9) will not be changed, but retarded. They don't appear immediately but only after a (short) while:

    {
      "lines": 5,
      ...
      "keystrokeDelayms": 100
    },

With the entry every relevant key pressed would be delayed by 100ms. Adding code would slow down quite a bit.

A missing value or 0 would switch off retardation. Values from 1 to 1000 are valid. (Delays of more than 1000ms seem impractical.)

Such delays are independent from inserting disturbances. It seems best to first delay and then insert additional characters.
