With GIMP, how do I hide all layers except the current one?

Version 2.6

Shift+ Click on the eyeball, on the layer you want to remain visible.

Version 2.8

Installed from http://www.noobslab.com/2012/04/install-gimp-28-on-ubuntu-1204-precise.html

sudo add-apt-repository ppa:otto-kesselgulasch/gimp
sudo apt-get update
sudo apt-get install gimp

Gimp 2.8 will still toggle visible layers using Shift+Click on the eyeball, but now with layers within Layer Groups Gimp will respect layers that are invisible, or visible within a Group, There is a discussion here by developers - 1

What this means is that when you make a layer invisible within a group, it will stay invisible when toggling visibility of other layers and groups.

Before toggle and after toggle, I am toggling the visibility of the layer pointed to by the red arrow- ----------------
Notice that the layer within the layer group stays invisible when toggling the other layers with Shift+Click

Now for the bad news, This also means that When trying to toggle the visibility of many layers Within a layer Group It does not work, only selecting the visibility of the group as a Whole,

Notice that I am toggling the visibility of the layer pointed to by the red arrow, yet only the layers outside the group are affected.

I have not found any workarounds for this behavior yet.

Press Ctrl+L and unselect layers that you want to hide from the dialog box that appears. This works in Gimp 2.8
