I had a mac-newbie friend ask me about scrolling to the top and bottom of the window in Terminal. Also, paging up and paging down. I gave him a satisfactory answer (basically hold down the fn key and use he up/down, left/right arrow keys), but he pointed out something I never bothered with before:
If you look under the View menu, there are keyboard shortcuts for these actions. The ones for page up and page down show a key combination of command plus some other keystroke (see the screen grab below, I don't have the rep to insert a picture directly into the post)
WHAT on earth are those funny up and down arrows with the perpendicular lines through them? What keys do they represent?
