how to disable (mute) a node in node editor ?

How can i mute/disable a node in node editor ? i want to temporarily exclude it from the calculation without have to detach the node. It’s very easy to debug this way , rather than have to detach node and relink back and forth.

Also , in node editor , for image texture node, i can’t find a way to preview it inside node editor. Should be a faster way to check what is inside this texture map intuitively without have to check the filename and use image browser. It will be great if there’s an image thumbnail showing what the image is.

Thanks.

Press (M) with the node selected.

Thanks a lot. I miss that one.
