Expected Behavior

Standard text selection should work in the chat output panel, either:

• Always (direct drag-to-select, like a normal chat UI), or
• With a documented modifier (e.g., Option + drag, the standard xterm.js bypass for mouse-events mode)

Selected text should be copyable via Cmd+C / Ctrl+C.

Suggested Fixes (any of)

1. Disable enable-mouse-events for the chat output panel — mouse-events mode is meant for interactive TUI apps, not chat transcripts
2. Ensure xterm.js Option-click selection bypass works as documented
3. Add a per-message copy button (hover-revealed) as a UX workaround
4. Provide a /copy slash command or "Export transcript" feature for the active session

Impact

Users cannot copy specific portions of agent output — code snippets, commands, URLs, file paths, etc. Current workaround is to copy the entire visible buffer to a text editor and manually trim, which is a significant productivity hit for a core chat interaction.

Steps to Reproduce

1. Start Hermes Agent WebUI
2. Open http://127.0.0.1:9119/chat
3. Have a chat session with some agent output
4. Attempt to select any portion of the chat output by clicking and dragging

Result: Nothing is selected.

Expected Behavior

Standard text selection should work in the chat output panel, either:

• Always (direct drag-to-select, like a normal chat UI), or
• With a documented modifier (e.g., Option + drag, the standard xterm.js bypass for mouse-events mode)

Selected text should be copyable via Cmd+C / Ctrl+C.

Actual Behavior

• Click-and-drag in the chat area selects nothing — no text is highlighted
• Cmd+C (with no selection) copies the entire visible chat buffer instead of a user-chosen portion
• Double-click and triple-click do not select a word or line
• Option + drag and Shift + Option + drag have no effect
• Right-click (two-finger tap) opens a context menu that copies only the single word under the pointer — not a usable selection range
• The chat output is therefore effectively read-only from a copy-paste perspective; users cannot extract code snippets, commands, file paths, or URLs from agent responses without copying the entire buffer and manually trimming in an external editor
