MacOSX X11 Defaults
If you use MacOS X and X11 then you can get a better look with scrollbars etc. by saving the following as the .XDefaults file in your home directory. (Note the period in the front of XDefaults to make this a hidden file). We suggest using the free text editor "TextWrangler" from the creators of BBEdit as this has the ability to open hidden files and save in other formats etc. In all an excellent text editor.
