I’ve had this problem ever since Function Graph was introduced.  How can I do a quick ‘fit all’?  I know there’s a ‘Auto Scale’ preference, but it’s not working the way I want.

But my main problem is that I want my camera to start and end at zero velocity.  But I have to drag, drag, drag, drag the Fuction Curve windowmagnifier icon to scale the grid to see the zero velocity axis.  I can spend 30 seconds scaling the windowmagnifier before I reach the zero axis.  I need a ‘fit all + zero axis’ command!
Please tell me there’s a better way!

Don’t know if this is what you’re looking for - however, from the EIAS 6.5 PDF Manual - Function Curve Editor Keyboard shortcuts -

Press the Option/Alt Key then click and drag to Marque select and zoom into an area.

Press the Option/Alt Key then Click on the Zoom Button to fit the selected curve to the window.

The other keyboard shortcuts are for manipulating key frames and the curve itself.

Hope this helps.
