How can I replicate Windows End/Home key?
Solution 1:
I used the following a lot.
⌘CMD+ꜛ: Home
⌘CMD+↓: End
⌘CMD+←: Beginning of Line
⌘CMD+→: End of Line
These I learned the other day from here - very handy for coding and writing, these are emacs bindings which work on Macs.
CTRL+A: beginning of line.
CTRL+E: end of line.
CTRL+U: delete from cursor to beginning of line.
CTRL+K: delete from cursor to end of line.
CTRL+W: erase word to the left.
CTRL+T: transpose characters around cursor.
Solution 2:
The shortcuts you're looking for are listed on this very handy article in the Apple KB. Hope it helps.
Solution 3:
With MacBook Air (the 2012 model at least) the best solution I found was the free KeyRemap4MacBook utility -- it lets you change the keyboard in many ways, and I settled with "fn + cursor left/right" for Home/End and "fn + up/down" for PgUp/PgDown.

Solution 4:
These can actually be mapped globally for most applications by creating entries in ~/Library/KeyBindings/DefaultKeyBinding.dict
But this guy created a handy little packaged script called Keyfixer that sets up the bindings in the way you describe (with some additional Control and Shift modifiers.) I threw it in my Dropbox and run it on any Mac I have to use. Since the preferences are per-user you don't have to worry about screwing up someone else's keys.
