looks like there's a typo

• left_button->set_tooltip_text(TTR("Scroll Left\nHold Ctrl to scroll to the begining.\nHold Shift to scroll one page."));
• left_button->set_tooltip_text(TTR("Scroll Left\nHold Ctrl to scroll to the beginning.\nHold Shift to scroll one page."));

That typo was my fault, I had it messed up when suggesting a change.

Those stopped automatically when the static check failed from the typo.
