+# The Find builtin (SPC f f) = `fd`, in-core: it arms the SAME tag input `/`
+# does, but Enter walks the pane's DIRECTORY instead of its text and writes one
+# matching path per row into a "+Search" OUTPUT BUFFER. Every row is therefore
+# an ordinary look target, which is the whole point: n/N step the rows and look
+# them with no code of their own, opening each found file, and focus returns to
+# the pane that owns the search so the next n keeps stepping. The walk skips
+# .git, matches the NAME case-insensitively, and sorts (readdir order is not
+# stable). `SPC f s` is Save, which moved out of `w` to make this group.
