- Left/Right arrow keys move cursor within text - Home/End jump to line start/end - Insert text at cursor position (not just at end) - Backspace/Delete work at cursor position - Paste inserts at cursor position - History browsing sets cursor to end - Visual cursor: inverse style on character under cursor - Hide terminal hardware cursor in normal input (use rendered cursor) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
