What is the outline method?
The outline method means writing bullet points with indentation — grouping and layering ideas by depth. The flow is: dump everything out → group into clusters → arrange into order. It lets you spread what’s in your head across a text file in a structured way.
Writing with hierarchy and order in mind reveals gaps you hadn’t noticed, and often makes you realize you need to reorder things by priority.
How to use it in TextTree
Press Tab to indent. Adjust indentation as you go to build up the hierarchy. You can select multiple lines and press Tab to indent them all at once. Press Shift+Tab to remove indentation.

The key is not trying to organize from the start. Dump all your ideas as bullet points first, then use Tab to layer them afterward — that’s the natural flow.
Usage patterns
Preparing for a meeting List what you want to discuss → group related items with indentation → reorder the agenda.
Drafting a report or proposal Locking in a skeleton outline before writing saves you from major rewrites later.
Untangling a vague concern Getting everything that’s bothering you into bullet points quickly reveals what the actual problem is and what’s still unclear.
One file per topic — for reuse later
An outline works best as one file, one theme. That way you can reuse it later.

When a similar project comes up, copying a past outline gives you a massive head start.
The value of simplicity
Unlike dedicated outline tools, TextTree’s editor stores everything as a plain text file you can manage in any folder. When the outline becomes a document, save it. When the project is done, archive the folder. Nothing extra needed.
