They learn their tools really well. I can't tell you how many good professional programmers I know that are utterly handicapped in their speed because they navigate the code base in an inefficient way, can't rename things quickly, can't catch something with the debugger, etc. Once a lot of those inefficiencys are gone it makes more mental room to think about the problem without distractions.
