This functionality can be found in NewEdit (http://wiki.woodpecker.org.cn/moin/NewEdit), first put the caret in middle of delimeters, such as ''""(){}[], then press Ctrl+E, the text between delimeters will be selected. And there are two direction of selection, left first and right first(Ctrl+Shift+E). If you press Ctrl+Alt+E again, the the delimeters will be selected. > > This is feature of BBEdit/TextWrangler on the Mac, which extend > selection to the nearest outer parenthesis.
