In the manual I misunderstood --title=name to specify a title rather
than the path. I find the variable $PWD does return the path, and I
can start mlterm with the command $ mlterm -T $PWD to get the path
displayed in the window frame.

However, if I put into ~/.mlterm/main the line: title=$PWD, what then
appears in the wndow frame is: "$PWD". Somehow I'm missing the syntax
for expanding that variable.

I found no help here.

My env has PWD=/home/haines, and so it seems $PWD should work.

The only content in ~/.mlterm are where I define geometry=80x24.
bg_color=linen,fontsize=13, Nothing about accepting shell strings. The
msg.log only reports not caring for my choices of font size when I
find installed mlgerm.

Yes, Launching it with -T $PWD & does return the current path.

Looked at these, but found no help here.

I'm too dense to see how this related to title.

the only config file I get is main. I found that Ctl=both mouse
buttons when mlterm open did raise a menu. None seemed of use. One
seems to have $SWP checked, but when I unchecked it I any access to
the configuration menu. Can't get it back.

I don't run any desktop environment, and so konsole not installed.

I did, and if I say title-$PWD, it is "$PWD" that is
displayed as title.
