:cw[indow]
:cope[n]
	Open a quick-fix (result-list) window
:cl[ist] [from] [, [to]]
	List all errors that are valid |quickfix-valid|.
	If numbers [from] and/or [to] are given, the respective
	range of errors is listed.  A negative number counts
	from the last error backwards, -1 being the last error.
	The 'switchbuf' settings are respected when jumping
	to a buffer.
:cn
:cp
	Go to the next/prev match (usually we map these action to hotkeys)
