[Pharo-project] Navigating around the source code

Hi all, I have a question (may be is a stupid/freshman question); How can I move around the source code (inside of OB Package browser)? For example (in almost any text editor of mac os x): cmd + (left arrow) == move to the begin of the current line cmd + (right arrow) == move to the end of the current line alt + (right arrow) == move to the next word in the current line alt + (left arrow) == ... and so on I was wondering If those shortcuts (or similar) work in Pharo.
