Re: Expectations for subshell

Which shell you are using? Is it working properly if you are NOT toggling 
"quickly" whatever that means?

The output of the command is not supposed to get lost, but it can 
disappear if something is interfering with alt mode, e.g. mc is running 
inside screen.

We try to support sensible shell integration with most popular shells 
(bash, zsh) and at least not completely fail on less popular ones (tcsh, 
etc.), but sadly there isn't really a way to do a robust shell 
integration, unless we implement a terminal emulator ourselves.

Unfortunately, this is not something we can even contemplate at the 
moment, so the best answer is to use the fragile pipe-and-alt shell 
integration knowing its limitations.
