<section begin=2.40-Animation-Basic-Tools-Ipo Curves and Keyframes />

change extrapolation type of ipo curves of actions

 added changing the extending / extrapolation type of the IPO curves of
 selected actions in the action editor

  Pose-constraint Ipos now are integrated in NLA

Autohandles clamping in IPO Window

 Autohandles in Ipo Window still could overshoot. Added a new clamping to
 ensure the handles never result in a curve that goes beyond the neighbour
 control points.
 
 http://www.blender.org/cms/Animation_Curve_Handle.717.0.html

 Ipocurves with "Auto" handles now have option to remain horizontal on the
 extrema (tops & valleys). Use ALT+H to set this per selected curve.
 Note this is a per-curve feature, not per-handle.

 - when there are edges in mesh, it now only copies selection in edges
   when you have selectmode edge

 Slightly altered rule for the new IpoCurve option "Keep horizontal on
 extrema". It now also keeps auto-handles horizontal when the Y coordinate
 is exactly identical.
 
 This option is default on inserting new curve/keys.

IPO constraints

 - Button "Show" will make the IpoWindow show the Constraint Ipo
  (it didn't before, when IpoWindow was not set to correct mode)
 
 - Button "Key" will insert a key point on current frame (and show it in
   IpoWindow)
 
 Note that both options will create an Action too, if it didn't already exist.
 So, without opening an IpoWindow you can already animate Constraints.
 (Todo: use the auto key option to always insert on changing slider)
 
 Selecting a Bone will update the Constraint IpoWindow too. Note
 however, that when there are multiple Constraint Ipos on a Bone, it only
 shows the first... will solve that later.

IPO action and nla cleanup

 Stage two of the giant animation recode project; Ipo/Action/NLA cleanup
 
 Impatient people can check the goodies in CMS:
 http://www.blender3d.org/cms/Action_and_NLA_editor.706.0.html

 Now the goodies;
 - made Actions to allow any Ipo type
 - made NLA to define active actions, for Action window too
 - corrected timing for active action, so it shows the 'real time', as
   defined in NLA editor.

 New option; "Lock Time to Other Windows" for Ipo, Action, NLA and Time
 windows. If set (in View pulldown), it synchronizes the horizontal scale of
 the current window with the other Windows with this option set. That way
 you always have these windows showing an identical part of the time you
 work on.
