I want to slow how fast you zoom in or out using the keyboard. I have tried changing fovspeed, keybfovchange and fovfriction in control settings. (eg. <control fovspeed="1" >) but these seem to have no noticeable effect on zoom speed.

BTW Klaus, I found that with keycodesin and keycodesout, putting a space as well as a comma between keycodes causes the code to not be read. If that is intentional, perhaps it could be included in the documentation.
