11.17. How come I have to hit CTRL+P twice to send CTRL+P once?

CTRL+P is the default ``force'' character, used to tell tip that the next character is literal data. You can set the force character to any other character with the ~s escape, which means ``set a variable.''

Type ``~sforce=<single-char>'' followed by a newline. <single-char> is any single character. If you leave out <single-char>, then the force character is the nul character, which you can get by typing CTRL+2 or CTRL+SPACE. A pretty good value for <single-char> is SHIFT+CTRL+6, which I've seen only used on some terminal servers.

You can have the force character be whatever you want by specifying the following in your $HOME/.tiprc file:

            force=<single-char>
