Ctrl + Up/Down to scroll through Terminal.app window In the Ubuntu terminal, Shift + PgUp/PgDn scrolls the window up or down a page, and Ctrl + Shift + Up/Down scrolls the window up or down a line. On my Mac, Shift + PgUp/PgDn works the same as on Ubuntu, but Ctrl + Up/Down triggers Expose instead. Is there a key combination that I can use in the Mac Terminal.app to scroll up or down a single line at a time?
