NetBeans – Filter output

Filter dialog box accessible via Ctrl + G shortcut in output window

NetBeans allows you to filter the logging output of an application, if you stumble upon the feature. I normally use the Find command in the Output window to search for occurrences of a string with the Ctrl + F (Command + F on Mac) shortcut, and then go to the next matching result with the Command + G shortcut when I’m searching for something in particular (e.g. a line logging the state of a variable in the program). I found that if you press Ctrl + G instead, you can filter the output to show only lines that match a given string or regular expression. This is an extremely useful feature, and one I only found by accident. I hope this helps any NetBeans developers out there.
