+Subject: [PATCH 1/2] Recognize Meta+Left and Meta+Right
+
+Recognize `Alt-Left` and `Alt-Right` for navigating by words in more
+terminals/shells/platforms.
+
+I'm not sure exactly where to find canonical documentation for these
+codes, but this seems to match what my terminal produces (macOS + iTerm2
++ Fish + Tmux).
+
+It might also be nice to have some more support for editing the bindings
+for these characters; sequences of more than one character are not
+supported by `el_bind_key` and similar.

+This patch is applied upstream: https://gerrit.lix.systems/c/lix/+/1883
