java-add-interface — human mapping

A painting is a person's account of this edit as text, recorded independently of the node mapping - a rendering often has several equally defensible answers where the mapping has one. Deletions and insertions carry no position on the opposite side in a painting, so that panel draws no caret for them.

Keybindings

j / k: next / previous visible node (tree panels)
h / l: collapse / expand the focused node
g / G: jump to first / last visible node
Tab: switch focus between Before/After panels
/: search: jump to next node whose text contains a given string
a: jump the other panel to this node's mapped counterpart
i: hide identical matches, showing only inserted/deleted/updated nodes and their ancestors
v: cycle the view: split / code only / tree only
p: cycle what the code view renders: the node mapping, then each human painting
r: mark this fixture as reviewed, or forget the mark (kept in this browser only)
n: open a random fixture not yet marked as reviewed
?: toggle this help
