How to link opened file with project tree in NetBeans

Just thought of adding what ax said:

The keyboard shortcuts in Windows are:

• Select in Projects : Ctrl+Shift+1
• Select in Files : Ctrl+Shift+2

The keyboard shortcuts in OS X are:

• Select in Projects : CMD+Shift+1
• Select in Files : CMD+Shift+2

As described in NetBeans "link with editor" feature, if you want the link to be permanent or persistent, use View | Synchronize Editor with Views. (In NetBeans >= 6.7.1, at least.)
