"/terminal-setup command missing in Alacritty terminal"

[arathald]

Bug Description /terminal-setup command isn't available on alacritty - I don't know if this is due to some limitation of alacritty, but the command not being available is confusing. I think at very least, the command should be available, and give a message that my terminal emulator isn't supported if that's the case.

Environment Info

• Platform: macos
• Terminal: alacritty
• Version: 1.0.3

This alacritty config seems to work (on Linux at least)

[keyboard]
bindings = [
    { key = "Return", mods = "Shift", chars = "\n" } 
]

[keyboard]
bindings = [
    { key = "Return", mods = "Shift", chars = "\n" } 
]

Can confirm that this config update does work for Claude running standalone in Alacritty but it does not work if Claude is running in a TMUX session. Looking more into this hoping to find a solution.

Are you sure? It works for me in a tmux session.

[keyboard] bindings = [ { key = "Return", mods = "Shift", chars = "\n" } ]

Confirmed this is working in Alacritty with or without tmux session

I confirm the issue is still here, I confirm the solution of @dk-nc works. Only the Claude integration is missing to remove the error

The error output by claude-code

Terminal setup cannot be run from alacritty.

     This command configures a convenient Shift+Enter shortcut for multi-line prompts.
     Note: You can already use backslash (\) + return to add newlines.

     To set up the shortcut (optional):
     1. Exit tmux/screen temporarily
     2. Run /terminal-setup directly in one of these terminals:
        • IDE: VSCode, Cursor, Windsurf
        • Other: Ghostty, WezTerm
     3. Return to tmux/screen - settings will persist
