channels in photoshop

[ramadane30620252]

in layers you can choose all layers b clicking on the first layer with the last using shift

but in channels we cant do that you have to choose every channel one by one

I am asking if there is any way to do that like layers selection

Thanks

The obvious question is why you would want to do that?  You select all three channels by clicking on RGB.  We usually look at the three channels one at a time to see which has the best contrast, or would make a good mask (alpha channel).  We might collect a few alpha channels if we storing several masks, but we wouldn't normally want to select more than one of them.

If I am misunderstanding you, can you explain some more about what you'd like to achieve?

I am talking about alpha channels not RGB channels.if I want to select all alpha channels like selection of all layers by clicking on the first layer with the last using shift

What exactly are you trying to accomplish. If you want to add to or subtract from a selection do so from Load Selection Drop Down Menu.

if I want to select all alpha channels

Do you want to select all the alpha channels, or load all the alpha channels as selections?

• For the former, click the 1st one, then Sh+click the others.
  
• For the latter, Ctrl/Cmd+click the 1st one, then Ctrl/Cmd+Sh+click the others.
  

clicking on the first layer with the last using shift

doesn't work in the Channels panel

Like Trevor, I'm curious about the workflow behind this question.
