Code view:
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.

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
