I've looked up words which mean "read quickly".
That's what I found:

1. read quickly to find a particular piece of information
scan, scan through

2. read quickly to get a general idea or what is it about
skim, skim through/over

3. read quickly to check that there are no mistakes or problems
take a look, look over

But I didn't find what exactly look through and glance at/over/through mean. Could somebody explain it? And there are probably other words that mean "read quickly". If so, I'd like to know them too.
