For a game I'm working on I'll need a freely moveable camera, a bit like the one possible with FirstPersonHandler:
With the middle mouse button (or scroll wheel) pressed, you can do mouse looking.
With the right mouse pressed, you can move left/right/up/down.
Using the mouse wheel, you can scroll in/out.
Within this handler, I'll need KeyUpAction and KeyDownAction, much like KeyStrafeLeftAction.
I feel that KeyUpAction and KeyDownAction (or KeyStrafeUpAction and KeyStrafeDownAction, if you like) are missing for completeness.
What do you think?
If needed, I'll post the code here so it can be checked in.
I second the sentiment.
Sounds useful
Alright, I just copied KeyStrafeLeftAction and KeyStrafeRightAction and modified them to use the other axis.
I don't mind if I don't show up as the author, and someone should maybe sort out the version - I wasn't sure wether to start at 1.00 or count up from 1.10. 
The Handler will be here within the next few days. Any suggestions for the class name?

Personally I feel the actions are good enough. People can use those to make their own handlers.
I basically made my own after browsing yours (copy paste edit locally was simpler than copying from the forum, hehe…) Should be in CVS shortly. Could you have a look over it to verify correctness?

For viewing you can use https://jme.dev.java.net/source/browse/jme/ .
Thanks for the link 
I've just done a test run with the code, and it works fine.

I haven't yet bothered to access the CVS... but I'll look into that :)
EDIT:
I just tried, and it seems that the local firewall doesn't let me through and the proxy doesn't support (or just blocks) the CVS access.
If there's a way to access the CVS through HTTP or FTP, I'll look at it, otherwise I'll just have to wait for it to be put into the next release.
