Default (global) indents

I’d like to set the default paragraph indent so that it applies to all indented paragraphs in all documents. It’s currently set for 1 inch, and I’d like it to be half that. I don’t see where to do this.

To be clear: this would be the indent spacing under the command:
Paragraph > Increase/Decrease Indents > Increase Indents

I’ve looked under File > Options > Editing > Formatting, and also under Project Settings > Formatting, but don’t see where indenting (as opposed to tabbing) can be set.

This is mostly to work around the unreliability of lists. Should I use tabs instead?

After GI to a file and adjust indent in format toolbar and believe in ruler. Move indent where you with chosen font, size etc.
Now go to Go file>options>editing and click in text window should have same settings as the file you were in and click set as default in upper right. That should set indent

Format > Paragraph > Tabs and Indents?
