vim/Keyshort/Fold

• Keyshort vim vim/Keyshort
  • Toggle the Fold Under the Cursor Card
    • Shortcut: za
    • Description: Opens the fold if closed, closes it if open. zA does the same recursively, so nested folds follow the outer one.
  • Open or Close One Fold Card
    • Shortcut: zo open, zc close
    • Description: Explicit single-direction versions of za. zO and zC apply recursively to every fold nested under the cursor.
  • Open or Close Every Fold in the Buffer Card
    • Shortcut: zR open all, zM close all
    • Description: Sets fold level to maximum or zero for the whole buffer. zM is the fast way to get an outline of a long file; zR restores it.
  • Toggle Folding Itself On and Off Card
    • Shortcut: zi
    • Description: Flips the foldenable option. Distinct from zR — zR opens folds while leaving folding active, zi suspends folding entirely and remembers which folds were closed when it is switched back on.
  • My Note
    • In my LazyVim config folding is foldmethod=indent with foldlevel=99, so files open fully expanded and folds follow indentation rather than syntax. That makes zM immediately useful on Logseq pages and Python, where indentation already carries the structure.
    • No nvim-ufo is installed, so zR and zM are the built-in commands rather than ufo's remapped versions, and there is no virtual text showing folded line counts.
    • Background on fold methods and treesitter-based folding: nvim/Q/How can I quickly collapse and expand a block in nvim?
