Total Commander

I make regular use of Alt-Shift-Enter to see the total file space in/under each directory. I then feel I am in a different mode, where TC uderstands that I want to see the total space of each directory.
It would be marvellous if this mode could be preserved as I change to different directories, higher or lower in the directory tree without having to repeat the Alt-Shift-Enter process.
If there is already a way of achieving this, I have not discovered it, and I apologise. If not, I earnestly request an enhancement.

Use Everything and you always have this numbers available while change dirs.

Configuration - Options - Operation - Calculate space occupied by subdirectories - Automatic (choose one of the three options, as preferred).

Christian,
Seems this option is not documented in the Help file?
