My cheat sheet for using the Atom editor with the FoldingText package. See official doc at https://jessegrosjean.gitbooks.io/foldingtext-for-atom-user-s-guide/content/editing.html

Must-do:

• Must choose File » New Outline and save as .ftml, to create an outline.

How-to:

• Hyperlink: Cmd-Shift-K
• All sorts of formatting: Cmd-Shift-P “Outline Editor: Toggle”
• Edit tags: t (or Cmd-Shift-t in Text Mode)
• Fold all to a given level: Edit » Folding
• Toggle fold: Cmd-period (or just period, if not in Text Mode)
• Toggle “complete” tag: Ctrl-space (or just Space, if not in Text Mode)
• Toggle priority: digits 1-9
• Indent: Tab
• Outdent: Shift-tab
• New line: Enter
• Fold: Click the triangle
• Unfold: Click the triangle
• Move: Drag the triangle (hold Option to copy instead of move). Hold Ctrl while dropping (not dragging) to copy a hyperlink back to the original. (Can link across files.)
• Enter Text Mode: press i or a or left/right arrow key or click where you want.
• Exit Text Mode: press Esc.
• Get full list of commands: Cmd-shift-P and type “outline editor”
• Focus on children: Cmd-Opt-Down
• Unfocus: Cmd-Opt-Up
• Filter by text: Cmd-F, then type string to match. Search syntax is at https://jessegrosjean.gitbooks.io/foldingtext-for-atom-user-s-guide/content/appendix_a_search_syntax.html
• Filter by tag: Click on a tag or use Cmd-F and search for the tag text (e.g. #mytag)

Formatting:

• Command-B to bold text.
• Command-I to italicize text.
• Command-U to underline text.
• Command-Shift-K to insert and edit links.
• Control-C to clear text formatting.

Concepts:

• Text mode: When a line is selected, you can’t change the text. You enter “text mode” to get an i-beam cursor.
• Focus: Show me just the children of this row.
• Filter levels is funky. This shows up most often if you put a “complete” status on a parent and filter for “not @status = complete”, and it will show you the complete parent if a child is incomplete.
