Enable displaying of key strokes without casting As far as I know you can enable displaying key strokes while you screencast for tutorials.

Is there a way to archive this without casting? I would like to have visual feedback which combos I pressed to make remembering easier.

Cheers!
You want to download and install the   screen cast key status tool plugin. It has been removed from the Blender download package. 

It displays the keys when enabled independently from recording a screencast or normal interaction.
