Re: [Matlab-emacs-discuss] up arrow not working as expected

It sounds like some sort of error is preventing the keymap from being reset. Start a fresh emacs, and try: M-x toggle-debug-on-error RET And then start a new Matlab shell. If that doesn't produce a stack trace, then, you will need to actually debug the matlab-shell command to see why it is not binding [up] to the right key. To do that, start a fresh Emacs, then do: M-x load-library RET matlab RET And then open up matlab.el, put the cursor on the line that looks like: (define-key km [up] Around line 4181, and type: M-x edebug-defun RET Followed by C-x x b (that sets a breakpoint.) Now run matlab-shell, and you can press SPC to step through the function, or g to go until a breakpoint. Hopefully this will expose why the keymap is not being set.

Subject: Re: [Matlab-emacs-discuss] up arrow not working as expected F1 works, and for the up-arrow gives: up runs `previous-line' `previous-line' is an interactive compiled Lisp function -- loaded from "/tmp/buildd/xemacs21-21.4.20/lisp/simple.elc" (previous-line COUNT) Documentation: Move cursor vertically up COUNT lines. If there is no character in the target line exactly over the current column, the cursor is positioned after the character in that line which spans this column, or at the end of the line if it is not long enough. The command M-x set-goal-column can be used to create a semipermanent goal column to which this command always moves. Then it does not try to move vertically. The characters that are moved over may be added to the current selection (i.e. active region) if the Shift key is held down, a motion key is used to invoke this command, and `shifted-motion-keys-select-region' is t; see the documentation for this variable for more details. If you are thinking of using this in a Lisp program, consider using `forward-line' with a negative argument instead. It is usually easier to use and more reliable (no dependence on goal column, etc.). I am using the latest version of matlab.el, compiled. thanks, maria On Mon, May 12, 2008 at 11:16 AM, Eric Ludlam <Eri...@ma...> wrote: > Hi, > > Mlint.el doesn't have anything to do with the shell mode. > > Perhaps you have found an older version of matlab.el? The latest version is on sourceforge in CVS. You can get it from http://matlab-emacs.sf.net. Go to the project page, then "Browse CVS". In CVS, you can download the latest versions. > > Also, it sounds like your Emacs has been configured to use C-h as a backspace key, and not for help.
