How to quit Vim quickfix?

I know that when you run :make in Vim, you can use commands to go through each error like :cn and :cp. However, I often find myself scrolling through warnings that I don't need to fix. Is there a way to quit scrolling through the errors/warnings and resume editing? (I have heard that you can set Vim to ignore warnings, but I've been told it's difficult so I'm looking for something easier).

You can close the quickfix window by running:

:ccl[ose]

If you want to open the quickfix window again (without having to run :make) you can run:

:cope[n]

Even if the quickfix window is not visible, you can still move forwards and backwards through the items in it with the commands :cn and :cp.

Personally, I find the :cn and :cp commands quite laborious to type, so I would recommend mapping them to something more convenient if you use them often. The unimpaired plugin provides sensible mappings for moving through the quickfix list:

[q   :cprevious
]q   :cnext
[Q   :cfirst
]Q   :clast

If quitting from that window is all you want you can do as suggested above

:ccl

or even simply

:q

in the errors window. Or you can simply switch windows ctrl-w+w ctrl-w+k...
