1. reading books like SICP [1], PCL [2], PAIP [3], ANSI Common Lisp [4]
   and others

2. reading articles like Paul Graham's to "get" the language

3. writing code

4. reading other people code

5. asking questions (e.g. on comp.lang.lisp)

of course it is (subseq). you may want to check this link [5]. if you
need something more powerful there is a regular expression package as
well [6]

you have to keep in mind that while the scheme standard is very small,
many implementations have more stuff built-in. 

OTOH, Common Lisp is a very big language with all sorts of control
mechanisms like dolist, do, dotimes, loop, and much more [7]. a very
flexible condition system (other languages have only "Exception
Handling") and a very powerful object system. All defined in the ANSI
standard. Check the standard and see for yourself [8] :-)
