        Now, i got it all work. Only thing missing is the GetNBit, cause I have not enough Time now. I'll post the full code later on. 🙂
        But a look in the SDK makes me think that CKeys doesn't have the function GetNBit because it's a method of the GeListNode Class.. ?

        PS: Still don't understand why you used an Invers Iteration.

        //edit:

        So, here's the complete function: 🙂
        Even with Undo-Functionality 😉

        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)  
          
          doc = op.GetDocument()  
          doc.StartUndo()  
          
          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()  
                      doc.AddUndo(c4d.UNDOTYPE_CHANGE,op)  
                      key.SetTime(curve,c4d.BaseTime(offset/fps+tme.Get()))  
              track = track.GetNext()  
          doc.EndUndo()  
          c4d.EventAdd(c4d.MSG_UPDATE)  
          
          return True
        

        Is there a bit for keys in the "usual" timeline ? This one does only affect the selected keys in the Manager .. Confused

        Cheers, nux

          Good job nux.
          I like how you implemented the other timeline windows.

          I needed to use a reverse loop in Coffee because if I had for example: keys ten frames apart and an offset value of ten. The first key would get moved on top of the last key. Then when the loop came around a second time. The keys were all on the same frame and it couldn't figure out what to move.
          I didn't know of any other way to do it.

          Deepshade,
          Just in case you don't know this. What nux posted is a method.
          So if you want to use this in the python script manager. You paste it above the def main section.
          Then call to the method like this:

            
          def main() :  
            obj = doc.GetActiveObject()  
            offset = 15 #change this value as needed  
            MoveSelectedKeys(obj,offset,timeln = 1)   
            
          if __name__=='__main__':  
            main()
          

          -ScottA

              Let me add, that in the SkriptManager op is automatically the selected Object. 🙂
              And you don't need to overload the timeln since you don't want timeline 2,3 or 4.
              So this works too:

                
                  
                  
                  import c4d  
                  def main() :  
                    offset = 15 #change this value as needed  
                    MoveSelectedKeys(op,offset)   
                    
                  if __name__=='__main__':  
                    main()

                  Hi all

                  Finally escaped from the last job.

                  A couple of things

                  1
                  Confusion
                  Just to confirm - the original concept was for staggered keys on multiple objects
                  Don't get me wrong - not complaining - just need to be clear what I'm seeing

                  The code is there in the while loop looks like it iterates through all the tracks of a single selected object.
                  If I select more than one object - nothing happens? (no provision in script so far)

                  2
                  I'd assume (if you want to modify keys differently for different objects) it would be better to write a small function 
                  and modify the Key value before running Key.SetTime(...etc 
                  dependent on the number of selected tracks
                  Sadly I cant see a way to return the count of selected tracks (yes Scott I now see the route) - so I guess 
                  the whole things needs to run in an outer loop - iterating through the selected objects?

                  Another issue  - if you modify the offset inside the While track loop
                  ie after
                  key.SetTime..
                  with something as simple as offset = offset + 10
                  Assuming you have a POS ROT SCALE tracks as well
                  Selecting all tracks is fine
                  Selecting just one track ie POS - inserts two extra sets of keyframes
                  as the while loop count is based on the total number of tracks
                  Cant see a simple solution

                  3
                  can't find reference to
                  C4d.NBIT_TL1_SELECT in the SDK - I take it these refer to the 4 timelines
                  Where did you get that info pls?

                    1:
                    You can simply use the function in an iteration through the selected objects.

                    What means staggered ? Don't know the word ^^

                    2:
                    Why modifieng the
                    key value ? I thought it's about moving keys ?
                    And what do you want to achieve with offset = offset + 10

                    Don't select a track, select the keys.

                    3:
                    It's in the GetNBits() function. Search for it without the c4d. in front.

                    I'll can answer your questions better later when im at home in about 2 hours.
                    Till then,

                          Hey Nux95

                          This is just great

                          And there's so much useful stuff here for reference
                          It's really appreciated  - many thanks

                          line 103 
                          op=list[i+1]
                          is throwing an error
                          index out of range

                          I guess this is just incrementing one object too many? at the end of the selected objects

                          Not wanting to take anything away from what you've done here - far beyond the call of duty 🙂
                          I think it would be nice to have the 'processing' part of the script possibly
                          in a function

                          ie release a collection of key manipulating scripts - by just changing the function

                          stagger - by offset - as we have now
                          stagger  - by total time - total time over which to stagger all frames
                          stagger exponentially large to small
                          stagger exponentially small to large
                          etc etc

                          cheers again

                            Do you recieve that message every time ? It didn't appear when I was using the Script.

                            I guess this is just incrementing one object too many? at the end of the selected objects

                            Shouldnt. 'op' is already the object with index 0, and 'i' starts with '0', so the next object for 'op' in the first iteration should be 1 => 'i+1'
                            But .. Hm, very bizarre. I didn't recieve that error, but as I think about it, that error MUST occure at the end of the loop.
                            Try it like this and tell me if the problen still exists:

                              
                            op = lst[i+1]   
                            if not op: break # Hopefully there is a 'break' expression for 'for'-loops. If not try something that stops the loop   
                            

                            stagger  - by total time - total time over which to stagger all frames
                            stagger exponentially large to small
                            stagger exponentially small to large
                            etc etc

                            Why not writing a Plugin ? 😉

                            cheers, nux

                              got rid of the index error

                              As far as writing a plugin. A bit beyond me at present, probably best to learn from your foundation work here Nux.

                                Next objective to 'nudge' everything back
                                as 'everything' gets moved over by staggering process
                                ie first track shouldnt move - everything else - stagger

                                    Does the Console tell you this ? O.o

                                    If A function calls itself, everything starts again. But you may have changed some values before. (Here the timeln variable)

                                          nope, not that - must be forum paste incorrect
                                          indent is as your example

                                          appreciate you can't test at moment

                                          I think its to do with this function setting op to the first object in doc
                                          if nothing selected
                                          that way op is never NULL

                                          def GetActiveObjects(doc) :
                                              import c4d
                                              lst = list()
                                              op = doc.GetFirstObject()
                                              while op:
                                                  if op.GetBit(c4d.BIT_ACTIVE) == True: lst.append(op)
                                                  op = GetHNext(op)
                                              return lst

                                            the list only gets appended if op is selected.
