[Pharo-project] How can I get smart characters in Pharo 1.4?

Hi guys. I cannot live without smart characters or whatever they are called. What I mean is when you select/surround something (a piece of text) and when you press '(' or '[', or whatever opening symbol, it adds both, the opening and the closing one to what you have selected. So...how can I have that in Pharo 1.4 ? Thanks -- Mariano http://marianopeck.wordpress.com
