How to display what key we are pressing in blender :
1. Download the python script at "https://svn.blender.org/svnroot/bf-extens...."
2. Import it to blender apps via" Ctrl+Alt+U - User preferences - Addons"
3. Enable the imported Addon, then turn it on in "3D view - Properties region (N) - Screen cast keys"
Or Copy & Paste the following code into notepad, then name it and save with Save As Type option is "All Files", DONE.
