57Selected text copies to your clipboard automatically on mouse release. To turn this off, toggle Copy on select in `/config`. With it off, press `Ctrl+Shift+c` to copy manually. On terminals that support the kitty keyboard protocol, such as kitty, WezTerm, Ghostty, and iTerm2, `Cmd+c` also works. If you have a selection active, `Ctrl+c` copies instead of cancelling.57Selected text copies to your clipboard automatically on mouse release. To turn this off, toggle Copy on select in `/config`.

59With a selection active, hold `Shift` and press the arrow keys to extend it from the keyboard. `Shift+↑` and `Shift+↓` scroll the viewport when the selection reaches the top or bottom edge. `Shift+Home` and `Shift+End` extend to the start or end of the current line.

133Mouse capture is the most common friction point, especially over SSH or inside tmux. When Claude Code captures mouse events, your terminal's native copy-on-select stops working. The selection you make with click-and-drag exists inside Claude Code, not in your terminal's selection buffer, so tmux copy mode, Kitty hints, and similar tools don't see it.139Mouse capture is the most common friction point, especially over SSH or inside tmux.

135Claude Code tries to write the selection to your clipboard, but the path it uses depends on your setup. Inside tmux it writes to the tmux paste buffer. Over SSH it falls back to OSC 52 escape sequences, which some terminals block by default. Claude Code prints a toast after each copy telling you which path it used.141Claude Code tries to write the selection to your clipboard, but the path it uses depends on your setup. Inside tmux it writes to the tmux paste buffer. Over SSH it falls back to OSC 52 escape sequences, which some terminals block by default. iTerm2 blocks them until you turn on Settings → General → Selection → Applications in terminal may access clipboard. Running [`/terminal-setup`](/en/terminal-config) in iTerm2 enables this for you. Claude Code prints a toast after each copy telling you which path it used.

143For a one-off native selection, hold your terminal's bypass modifier while you click and drag: `Option` in iTerm2, or `Shift` in most Linux and Windows terminals. The modifier tells your terminal to handle the selection itself instead of forwarding mouse events to Claude Code, so `Cmd+C` and your terminal's other copy shortcuts work on it.
