Sometimes, you need to adjust the location of a specific bone, but you don’t want to move all its children as well (child bones and art layers). In this case, with the bone selected, toggle the Edit Mode using Duik.
Duik will automatically and temporarily unparent all children so you can easiy relocate the bone, and then deactivate the edit mode.
Although the Edit Mode button in the bones panel works only for bone layers, there is another Edit Mode button in the Links and Constraints panel working for all layers.
When the edit mode is toggled, the bone name changes and it turns red to warn you, until you switch it off.
The forarm bone has been toggled to the edit mode.
In current versions of Duik, the edit mode does not work if the bones have already been rigged with the Auto-rig or other constraints.
