[mesa-users] Question

Thanks!   This makes me think there should be a place on the website for users to share "how to" ideas for viewing histories and profiles -- perhaps including simple scripts for some of the popular plotting options.  Would that be useful?  at least to folks just getting started?   We should make it easy for new users to make plots instead of digging into text files.

By default, if you scroll down with your mouse or press Page Down, your cursor will reset to the beginning of the row, which makes it annoying to try and see how a given variable changes over time. The emacswiki tells you what to add to your .emacs file to get around this,

I didn't even think of that since I never look at the text files (I make plots plots and more plots).  But in the rare cases where I do check something in the editor, I can set it so that it doesn't break lines of the file onto separate lines on the screen (same as your nowrap).  Then I simply use horizontal scrolling.   Or if I want to get several values from a row, I'll copy it to a separate file and replace spaces by CR's.  then do the same for the line with the column names and match up names with values.   It might be useful to have a script that would do that automatically, but I don't resort to doing it enough to be motivated to create such a script!
