Get selected keyframe

If i have one or more keyframes selected in the timeline, how can i access them in python? I'm trying to figure out how to change the angle of the seleceted keyframes handles. But I can't even figure out how to get the user-selected keyframe :)

Thanks. I've seen those.
The first links solution is sort of what i'm looking for but it only works if you have an object selected first. I need to run my code by only selecting one or more keyframe(s) in the timeline. If possible.
The second link is for listing the selected objects "Keyframe Selections" This is a way to set what parameters are animated when recoding new keyframes.

unfortunately I'm not aware of a shortcut to directly access the selected keyframes. But Niklas' MoveSelectedKeys function works nicely regardless of the selection state of an object. So you can iterate the object (or materials, shaders,...) hierarchy and use roughly Niklas' code to find the selected keyframes.
I will forward the idea for a convenience function to development.

Wonderful. I'm using Niklas's code for the time being.
But it would be very handy having such functions available.

Holy mackerel, that's an old post @gr4ph0s linked. Note that there's a bug in MoveSelectedKeys() if
you pass a value for timeln not in the range [1..4].
def MoveSelectedKeys(op,offset,timeln = 1) : # offset in frames import c4d if (not op) or (not offset) : return False if timeln == 1: timeln = c4d.NBIT_TL1_SELECT elif timeln == 2: timeln = c4d.NBIT_TL2_SELECT elif timeln == 3: timeln = c4d.NBIT_TL3_SELECT elif timeln == 4: timeln = c4d.NBIT_TL4_SELECT else: import math timeln = math.fmod(timeln,4) MoveSelectedKeys(op,offset,timeln) **return # <<< missing** doc = op.GetDocument() track = op.GetFirstCTrack() if not track: return False fps = float(doc.GetFps()) while track: curve = track.GetCurve() cnt = curve.GetKeyCount() for i in xrange(cnt) : key = curve.GetKey(i) if key.GetNBit(int(timeln)) == True: tme = key.GetTime() key.SetTime(curve,c4d.BaseTime(offset/fps+tme.Get())) track = track.GetNext() c4d.EventAdd(c4d.MSG_UPDATE) return True
