You can group as many commands as you like, as in

Indeed, and doing so can be useful, but in analyzing data interactively, one generally types a command (or two), examines the output, and then types another. Frankly, it's not so much the typing (as Doug Bates pointed out, one can recover previous commands) as the inability to forget about the data frame that seems the issue to me (and a small one at that).
