$EDITOR support for editing multi-line prompts #1376
Description
Describe the feature or problem you'd like to solve
Currently, /terminal-setup only supports VS Code, Cursor, and Windsurf, leaving terminal-only users unable to edit multiline prompts with Shift+Enter / Ctrl+Enter.
Proposed solution
Problem:
- Users in pure terminal environments (wezterm, iTerm2, tmux, etc.) have no way to compose or edit multiline prompts before submitting to Copilot CLI
- This forces users to either break complex requests into multiple single-line turns or switch to an IDE
Requested Feature: Add multiline prompt editing support for terminal emulators by:
- Supporting $EDITOR / $VISUAL environment variables to launch vim, nano, or other editors
- Allowing users to edit prompts in their preferred editor before submission
- Or implementing a portable terminal-based solution that works across common terminal emulators
Expected Behavior: Users in terminal-only environments can compose complex, multiline prompts using their preferred editor, similar to how git commit works without -m.
