Simply Maya User Community - View Single Post - Selecting every second keyframe

Run this code in a Python tab. The "2" popping up throughout the code just means that while looping through the list, it will act on every other item, essentially its your "nth item" value. Let me know if there are any issues.

Code:

import maya.cmds as mc

object = mc.ls(selection =True)[0]
keys = mc.keyframe(object, query =True)

i = 0
while i < len(keys):
	mc.selectKey(object, k =True, time = (keys[i], keys[i]), add =True)
	i = i+2
print "Selected " + str(len(keys[::2])) + " keys: ", str(keys[::2])
