Pi Keymap Tweaks

Opinionated editor and message-submit key tweaks for Pi.

Features

• Makes Enter queue a follow-up and Alt+Enter steer the current run.
• Normalizes terminal LF Enter input to submit correctly in SSH/TMUX sessions.
• Prevents Up from recalling prompt history while a non-empty draft is open.
• Uses Pi's configured app.models.clearAll key (recommended as Ctrl+X) to copy and delete the current editor line.
• Adds Codex-style line start/end behavior for Pi's configured tui.editor.cursorLineStart and tui.editor.cursorLineEnd actions:
  • line start moves to the previous line when already at column 0
  • line end moves to the next line when already at the current line end
• Supports cycling thinking levels backward, unbound by default and configurable via extension settings or Pi keybindings.

Recommended keybindings

This extension provides behavior; key assignments still live in your Pi keybindings config.
