This is from the "Readline Notation" section of the bash(1) man page:
In this section, the emacs-style notation is used to denote keystrokes.
Control keys are denoted by C-key, e.g., C-n means Control-N. Simi
larly, meta keys are denoted by M-key, so M-x means Meta-X. (On key
boards without a meta key, M-x means ESC x, i.e., press the Escape key
then the x key. This makes ESC the meta prefix. The combination M-C-x
means ESC-Control-x, or press the Escape key then hold the Control key
while pressing the x key.)

Yes, this is particularly tricky. Most of the time you don't need to worry
about which key sequences your particular terminal is sending because of the
use of libraries like termcap or curses which hide the differences. If you
are interested in the details you are looking for either ANSI or VT100
escape sequences. Here's one link that details the sequences (you'll have
to do a bit more searching if you want a textual explanation).

Quoting from the bash(1) man page:
quoted-insert (C-q, C-v)
Add the next character typed to the line verbatim. This is how
to insert characters like C-q, for example.
