With the exception of keyboard macros, this works for all commands that
take arguments off the stack. (To avoid potentially unpleasant behavior,
keyboard macros ignore the @kbd{K} prefix.) As another example, @kbd{K
a s} simplifies a formula, pushing the simplified version of the formula
onto the stack after the original formula (rather than replacing the
original formula). Note that you could get the same effect by typing
@kbd{@key{RET} a s}, copying the formula and then simplifying the copy.
One difference is that for a very large formula the time taken to format
the intermediate copy in @kbd{@key{RET} a s} could be noticeable; @kbd{K
a s} would avoid this extra work.
a @kbd{K} prefix before a keyboard macro will be ignored. A @kbd{K}
prefix called @emph{within} the keyboard macro will still take effect.)

Even stack manipulation commands are affected. @key{TAB} works by
popping two values and pushing them back in the opposite order,
