Indeed.
As it is not the first time, users did not "find" this, I have
made the links a bit more visible (for future R versions), now.
I'd use '(s)' instead of 's' [and more often and
importantly, I have a variable 'n' somewhere and need to use
'(n)' very regularly.
For smallish situations, btw, the use of ls.str() comes very handy.
It has to be noted that unfortunately, the difference between
'n' and 's' and 'c' has been a bit "blurred" for byte compiled
functions, and as the default JIT level is high, I had
occasionallz wanted an easy way to revert the byte compilation
before debugging or another way to get rid of this
drawback..

There are several commands available. Type "help" to see them:

You want "n", and are getting "s". I believe if you hit Enter without choosing
one, it will do the same as the previous time, so you've probably used "s"
sometime in the past.
