Where are Home, End, Page Up, Page Down on MBP keyboard?
I just bought a MBP-15 after spending my entire computer life with Windows. I have a fairly sophisticated spreadsheet that I created in Excel that I now want to use in Numbers. But I'm hung up on the simplest thing - Home & End. I've read other postings and guides related to the keyboard, but everyone else seems to indicate that there are already Home & End keys (and Page Up/Page Down keys) on the keyboard. I have none - at least none that I can find. I just have the standard MBP keyboard, including the F1-F12 function keys (plus fn, option, control, command, & arrows). All of the key remapping posts talk about their use in text like a Safari e-mail. For spreadsheets, Windows lets me take a formula in 1 cell, ctrl-c to copy it, then shift-end-down and ctrl-v to paste that new formula to the end of the existing column. How is this done in the Mac world? Very frustrating so far. If it matters, I'm using Numbers '09 with Lion. Any and all help appreciated.
