Rectangular Selection

By Petr on Oct 20, 2011

If you use development build, you probably noticed that NetBeans editor added Rectangular Selection action. I don't need this functionality every day, but it can be helpful in some case. One of such case is when you need to delete line numbers in a text or code copied from a tutorial. Like on the picture below.

You can select the rectangle after pressing Rectangular Selection toggle button in the editor toolbar or pressing CTRL+SHIFT+R shortcut.

The selection can be easily done with mouse or keyboard. When you use keyboard, just place the caret on a corner, keep down SHIFT and with the arrows keys you select what you need.

When the selection is done, you can easily delete all the line numbers with pressing DELETE key. Then you have to exit from the rectangle selection mode (CTRL+SHIFT+R or toggle button in the editor toolbar).

If you write a text , then the text is placed on every line in the selected area. This can be useful for example for changing access modifiers of more fields in a class at once.
