8.2 ‘kill-region’
=================
The ‘zap-to-char’ function uses the ‘kill-region’ function. This
function clips text from a region and copies that text to the kill ring,
from which it may be retrieved.
The Emacs 22 version of that function uses ‘condition-case’ and
‘copy-region-as-kill’, both of which we will explain. ‘condition-case’
is an important special form.
In essence, the ‘kill-region’ function calls ‘condition-case’, which
takes three arguments. In this function, the first argument does
nothing. The second argument contains the code that does the work when
all goes well. The third argument contains the code that is called in
the event of an error.
