Quickly Selecting Data from Salesforce Using System Log

If you just want to quickly see some data in your salesforce instance, you can execute soql queries by opening the Setup-> "System Log" and type in the following

System.debug ( [select Dealer_group_display__c from Account where Id = '001M0000005OFab']);
System.debug( UserInfo.getSessionId() );

This saves you from opening the Apex dataloader.
