Hey... Thanks for the help.
I didn't think to go looking for a windowmaker site. There is indeed a 'menu' file under /home/username/GNUstep/Library/WindowMaker. (such an obvious thing.
)
However, I also discovered a '.screenrc' file in the home directory that looks like it is more detailed in the options for xterm.
At least I got past this hurdle and I can now look in these two places for more info.
And this was just a part of my continuing WTF stack. This came up while I was getting familiar with where files are. I started at /bin, /boot, etc... And just hadn't got to the /home directory (at this sitting and although I have created that .bashrc and .bash_profile in the home directory). I should go back and start there.
The learning continues!
Thanks again...
Edit: And, when I originally posted to this thread, I had been searching, I thought, in the 'slackware' forum and thought that's where I was when I posted here.
