Closing gaps between lines

[NodaProductions]

Version: 2008

When I type a document and mistakenly hit return before I want to, how do I bring the line back up to where I want it? Every time I hit Delete, which is how I would do it in PC, the top lines begins deleting instead of closing the gap.
Surely there is a simple procedure, but I can't find it in HELP.

 

[Michel Bintener]

Backspace (the key just above the return key) always deletes characters by
going back; if you want to delete characters that are to the right of your
text cursor, just hold down the Function (fn) key and then press the
backspace key.

Please note that keyboards vary quite a lot (Is it a laptop keyboard? Is it
an older keyboard with a numeric keypad? Is it the keyboard that comes with
the new iMac models?); in order for us to be able to help you, you need to
provide us with as much information as possible.
