I found there is vi keybinding module for NetBeans editor. The announcement can be found in
nbusers mailing list.
0.8 is now available for download, it's the first verion to support NetBeans.
Installation is easy, you can download zip file and install local two
nbm files from Update Center Wizard. After restarting NetBeans, vi
editor mode is enabled.To disable the module, you can use Module Manager but it will require
to restart NetBeans in this version. See the documentation in zip file
for functionalities and such limitations.
To run command and input something e.g. for text search, another popup is
brought up around the bottom of NetBeans editor.
