+While mouse capture is on, your terminal can't do its native click-and-drag selection. Press <kbd>v</kbd> to enter visual select mode — this releases the mouse so you can select and copy lines from the diff (the footer shows `visual select`); press <kbd>v</kbd> again to restore mouse scroll/click. Tip: in side-by-side mode the selection spans both columns — switch to unified with <kbd>s</kbd> first, or use your terminal's block-select modifier (Option+drag in iTerm2 / Terminal.app, Alt+drag in many Linux terminals).
+
+Most terminals (iTerm2, Terminal.app, Alacritty, kitty, WezTerm, GNOME Terminal) also let you hold <kbd>Shift</kbd> while dragging to bypass mouse capture without toggling.
