there is _OneLayerOn and _OneLayerOff in the Layer toolbar. Personally i prefer to use cluster buttons like this, for the left button command to hide things:
_Select _Pause _-Invert _-Hide "TmpHide1"
and for the right button command to show what has been hidden:
it can be found in the “Hide Cluster” toolbar. You can create as many clusters as you like and it is not limited to layers. It also keeps things hidden which have been hidden previously.
if you select a single layer in the layer panel, click on the filter button and choose “Selected Layers”, to get back, click on the (now red) filter button again and choose “All Layers”. (this will not show / hide layer content, only the layers displayed in the dialog)
