Moving animation keys in python or hscript

I am writing a small animation tool that moves animation keys around. I am using “chkeymv” hscript command to do that. It works fine but I simply cannot retain the original user key selection in the animation editor. The selection always changes after.
I have also tried using python hou.Keyframe class by calling setFrame and calling hou.Parm.setKeyframe() and then deleting the old key but of course the selection also can't be retained.

Is there any way to retain the original key selection after calling “chkeymv” or is there any way to make Animation Editor keyframe selection in Python or Hscript?

Thanks in advance.

Hello,

I tried to use hou.setFrame() to extract the values of the Detail/Global Attributes changing with each frame in a text file but python doesn't seem to update these values. Moreover it appears to launch several times the script linked to the size of the loop.

If someone have a solution and can explain to me why this doesn't work, I would be more than grateful.
Bests regards,
Tiber

node = hou.pwd()
geo = node.geometry()

# CONFIG
filename = "/home/DetailAttribs.txt"
separator = ";"

# Set Frame
for frame in range(1,500,1):
    hou.setFrame(frame)

    if hou.intFrame() == 1:
        # Get File
        f = file(filename, "w")
        # Insert Columns
        for attrib in geo.globalAttribs():
            if (attrib.name() == "ModifiedCamClay") or (attrib.name() == "P"):
                attrib_count = attrib.size()
                if 1 != attrib_count:
                    for i in range(0,attrib_count):
                        if i > 2:   # if its a Multi Array
                            f.write(attrib.name() + "[" + chr(94 + i) + "]" + separator) # ASCII to Char
