RGB channel selection shortcut for tex editor

When editing a texture in the texture editor I usually need to have a look at what the individual channel looks like in my image.
It’s really frustrating to have to un-click the R and G channels just to take a look at the B channel.
I constantly find myself wishing there was some shortcut to switch between the channels easily.
If there is such a shortcut please forgive me I have not found it!

Thank you for your time:)

Seems like this has been buried and forgotten, so I made a thread in the forums: RGB Channel Selection Shortcut for Texture Editor - Feedback for Unreal Engine team - Unreal Engine Forums

Under Editor PreferencesKeyboard ShortcutsTexture Editor you can bind you own keys to toggle the visibility of each channel of your texture. There are 4 specific commands you want to bind:

  1. Alpha
  2. Blue
  3. Green
  4. Red

I’m currently using CTRL+1 = Red; CTRL+2 = Green, CTRL+3 = Blue, and CTRL+4 = Alpha

Thanks! Didn’t know about that!
It’s one step closer to what I want, but I wish it isolated the channel I’m toggling and not just turn it off. More like the bahavior is in applications like Nuke.
