global-font-lock-mode RET" or by customizing the variable
`global-font-lock-mode'.
** Unexpected characters inserted into the buffer when you start Emacs.
See eg http://debbugs.gnu.org/11129
This can happen when you start Emacs in -nw mode in an Xterm.
For example, in the *scratch* buffer, you might see something like:
0;276;0c
This is more likely to happen if you are using Emacs over a slow
connection, and begin typing before Emacs is ready to respond.
This occurs when Emacs tries to query the terminal to see what
capabilities it supports, and gets confused by the answer.
To avoid it, set xterm-extra-capabilities to a value other than
`check' (the default). See that variable's documentation (in
term/xterm.el) for more details.
