How to disable / configure realtime error checking in Netbeans

I am working with vim where I did key mapping (CTRL + L) to start error checking. Fact - realtime error checking is as useful as it is sometimes annoying, so I would like to know if there is a similar approach in Netbeans (I am using version 7.2.1, coding in PHP).

Here's the desired behavior:

• Don't check for errors automatically;
• Have some key mapping and / or menu action to manually check for errors.

Is it possible?

TIA,
