You'll notice
Claude Code now recognizes st and rxvt terminal families for correct key handling
What
Two new checks detect when the terminal is st (the suckless terminal) or part of the rxvt family, by matching the TERM environment variable. These are used when setting up how escape-prefixed keys are interpreted, so pressing Alt-plus-key is recognized correctly on these terminals.
Why
Without recognizing these terminal families, Alt key combinations could be misinterpreted, so this fixes key handling for people using st or rxvt-based terminals.
