How to move a layer without deselecting it

[asdfg123]

It's a problem occurring frequently If the contents of a specific layer is comprised of thin, short or small objects, brush strokes etc. and I need to move them.
When I try to select them (in order to move them), many times the mouse goes a little to the side of the objects (because they're so thin/small) and clicks on the object(s) on the layer beneath. This also has the unwanted side-effect of automatically deselecting the current layer.
Isn't it possible, once a layer is selected, to click and drag anywhere on the canvas to move its contents without deselecting it, like in Photoshop?

If you're using the "Move" tool just hold down the Shift key and it will only move the currently selected layer. So you click anywhere and only the selected layer will move.

If you're using the pick tool, holding shift or ctrl will prevent the tool from selecting another layer but avoid the control nodes or you'll transform the layer. And it won't move unless you're clicking inside the box.
