`Space x o`	Open the immediate Tree-sitter document outline
`Space x x`	Toggle the syntax fold at the cursor
`Space x f` / `Space x u`	Fold / unfold all syntax regions in this pane
`Space x [ f/c/p`	Go to the previous function / class / parameter
`Space x ] f/c/p`	Go to the next function / class / parameter

Bounds. Expansion keeps Tree-sitter’s half-open bounds. Relationship commands and the syntax text objects show them with the block cursor on the last included character, as in Select mode. Yank, delete, change, and indent act on exactly the highlighted span.
Folds are per pane. Two panes may collapse different regions of one shared buffer. Any edit clears both panes’ folds.
Folded rows show an accent-coloured ▸ between the line number and the gutter rule, and a muted … N lines suffix counting the hidden rows.
While parsing. Space x commands and mm are dimmed until the syntax tree is ready; see Syntax highlighting .
