Select the wall to edit, make sure the wall tool is active, then CTRL click on the skin you want to end at.
If the wall is short it will extend to that skin.
If it is too long it will split at that skin and you can delete the part you don't want.
I am not aware of a way to cycle through the skins on PC.
Or of course you can use Adjust (CTRL -) and click the skin you want to trim too (as described above).
Then you don't need the wall tool active and it automatically deletes the split part of the wall if you are adjusting a wall to be shorter.
