These keys are defined and handled by your terminal, not bash. 
Ctrl+C sends a SIGINT signal. See man bash, section SIGNALS on how 
bash handles it. Ctrl+D sends EOF (end of file). See the output of 
'stty -a' for other keys that are handled by your terminal before 
they even reach bash.

Note that for example Ctrl+S stops execution, while Ctrl+Q resumes 
it. In the bash manual you'll find that Ctrl+S is bound to the 
readline function forward-search-history by default, but since the 
terminal already handles this keyseq, it never 'gets through' to 
bash unless you'd disable/change it for your terminal via stty.

So these keys aren't documented in man bash since they aren't part 
of bash (or readline for that matter).
