SQL Developer tip: Don't open the table

One of things I don't like about Oracle SQL Developer is that if you are browsing and clicking on tables, it can automatically open the table on the right side of the IDE.
There is a simple way to switch that off, just heard how to switch this feature off. Navigate to the Preferences settings:

Goto Database >> Objectviewer, and uncheck the tickbox labelled "Open Object on Single Click"

And that's it.
