+An alternative to killing and yanking stack entries is using
+registers in Calc. Saving stack entries in registers is like
+saving text in normal Emacs registers; although, like Calc's kill
+commands, register commands always operate on whole stack
+entries.
+
+Registers in Calc are places to store stack entries for later use;
+each register is indexed by a single character. To store the current
+region (rounded up, of course, to include full stack entries) into a
+register, use the command @kbd{r s} (@code{calc-copy-to-register}).
+You will then be prompted for a register to use, the next character
+you type will be the index for the register. To store the region in
+register @var{r}, the full command will be @kbd{r s @var{r}}. With an
+argument, @kbd{C-u r s @var{r}}, the region being copied to the
+register will be deleted from the Calc buffer.
+
+It is possible to add additional stack entries to a register. The
+command @kbd{M-x calc-append-to-register} will prompt for a register,
+then add the stack entries in the region to the end of the register
+contents. The command @kbd{M-x calc-prepend-to-register} will
+similarly prompt for a register and add the stack entries in the
+region to the beginning of the register contents. Both commands take
+@kbd{C-u} arguments, which will cause the region to be deleted after being
+added to the register.

+The command @kbd{r i} (@code{calc-insert-register}) will prompt for a
+register, then insert the contents of that register into the
+Calculator. If the contents of the register were placed there from
+within Calc, then the full internal structure of the contents will be
+inserted into the Calculator, otherwise whatever text is in the
+register is reparsed and then inserted into the Calculator.
