It's a<br> list of strings that are mapped to functions in a keymap%, where the<br> string is eventually converted to a function through the<br> `call-function' method of keymap%. The extra level of indirection is an<br> ugly artifact of the days when parts of the GUI toolkit were<br> implemented in C++.<br> <br> <br> For text-editor methods, look here:<br> <br> <a href="http://docs.racket-lang.org/gui/text_.html" target="_blank">http://docs.racket-lang.org/gui/text_.html</a><br> <br> I think you want to use the `move' method.<br> <br> </blockquote></div><br> </div>
