Keyboard scroll-back not available in alternate screen buffer #3470

Problem

When running the Copilot CLI, the terminal uses an alternate screen buffer which disables normal keyboard scroll-back (Shift+PgUp, Ctrl+Shift+Up, etc.). This makes it difficult to review prior output without a mouse.

Current workarounds

• /search to find content by keyword
• Ctrl+O / Ctrl+E to expand collapsed timeline entries

Request

Please consider one of:

1. Adding keyboard shortcuts for scrolling within the CLI viewport (e.g., Shift+PgUp/PgDn or similar)
2. Offering an option to disable the alternate screen buffer so native terminal scrollback works
3. A pager-like scroll mode (similar to tmux copy-mode) activated by a keybinding

Environment

• OS: Windows 11
• Terminal: Windows Terminal
• CLI version: 1.0.52-1
