Searching the web gave me this terminal command:
defaults write -g NSNavPanelExpandedState ForSaveMode -bool TRUE

Entering it produces: Unexpected argument -bool; leaving defaults unchanged.

Changing TRUE to YES gave the same result.

It is supposed to set Save dialogs to the "long form", so you don't have to click the disclosure triangle to get a different view of possible locations in which to save.

While you're at it, how about a line that will do the same thing for Print dialogs. Something that defaults to the mode where the "Details" are not hidden in the dialog box.

Thank you one and all.

I think deleting this space - State For - turned the trick.

Edit: Yep, it did!

Many thanks for that.

Edit 2: And for printing, search for "expand" here. (I'm not certain it's what you're looking for.)

Thanks, Artie.

Those commands were accepted. Coincidentally I had used the 40 version of your 101 link.

For anyone else interested in the expanded print dialog, and don't want to search through 101 choices (actually a "Find 'Print' " did it very quickly), the command is:

defaults write NSGlobalDomain PMPrintingExpandedStateForPrint -bool true

And thank you for asking the question.

The 40 version?

Your link was 101 terminal commands. I had perused one with 40 commands, none of which were what I was seeking.

so was this resolved or was there still a question/problem?

Resolved. Thanks.
