My desk is a little too narrow for the long type of Apple keyboard -- the one that has the keypad and the Home ↖, End ↘, Page Up ⇞, Page Down ⇟ keys... (it will take up the space for the mouse).

So if the small (wireless) keyboard is used, is there a way to simulate these keys: Home ↖, End ↘, Page Up ⇞, Page Down ⇟? (Home ↖ takes a user to beginning of page, End ↘ takes the user to end of page).

In some apps like Chrome and Safari, Command ⌘ + Up ↑ is like Home ↖, and Command ⌘ + ↓ Down is like End ↘. Fn + Up ↑ is like Page Up ⇞, Fn + ↓ Down is like Page Down ⇟, but it won't work in some apps such as in Finder (File Manager) and iTunes, where both of them will only do PageUp and PageDown simulation but not Home ↖ orEnd ↘ simulation.

I have this keyboard:

Not this keyboard (which has the dedicated Home ↖, End ↘, Page Up ⇞, and Page Down ⇟ keys):
Apple extended keyboard

The Command+Up/Down keys you mentioned for Chrome and Safari are coincidences. The Fn+Up/Down keys are not. Those key combinations are actually mapped to the Page up/Page down keycodes, so the application thinks you actually pressed those keys. There are similar mappings for Home and End: Fn+Left and Fn+Right, respectively. These Fn+Arrow mappings will work exactly like Page Up/Down and Home/End in any application, unless it somehow is working around the system.
