Temporarily turn off certain key frames?

Hello everyone!
Does anybody know if there is a way to turn off certain key frames in Blender’s dopesheet?
They shouldn’t be visible anymore or marked as inactive and not have any effect on the active keyframes.

Many thanks for any hints,

I don’t know if it’s possible to mute specific keyframes but you can try muting the channel itself by clicking the speaker icon for the bone. For the visibility thing you can try selecting the bones you want to see and toggling the arrow icon in the dopesheet (to the right).

Thanks a lot for your suggestion! I would have to mute only some of the key frames on some of the channels and not the complete channels, though. But it’s good to know channels can be muted! Concerning the visibility, if I understand you correctly, your suggestion is also targeting complete channels, right?
