I misled the mouselabels demo, I have execute it on wxt and windows terminmal on windows.
That worked but echo back 'paused' to the command screen at each key stoke.
This is not a bug but it is annoying.

I have execute mouselabels demo on qt terminal on Ubuntu 12.04 LTS.

It partially work. Key input reflected in the plot window.
However, <del>, <bs> and <esc> work but <tab> does not work.

The qt terminal seems to have bug for key input handling but behave differently on windows and Linux.
