This is the second time I got that unloved "Stop! Look and Listen" for a question I voted to close after reading it several times and trying to understand it.
The question really is not clear to me: it seems he is asking for a shortcut like ALT^ that switches between windows of the same application, but then he states Oscar goes to tmux - which left me only with several ???.
My first version for the post used much stronger language :-)
After having read several comments I want to point out that I didn't want to discuss if this question should be closed or not - my purpose was to show that it is entirely possible for one question to be regarded as good by some reviewers and as bad by others - all acting in good faith - so those audits (in the close queue) eventually will go wrong.
