问题 I've been searching with no results for an integration of bash inside vi, as featured in emacs; the problem is: I have vi open with 2 views, one open with :split command, and I want to use bash through the second view, while I'm editing a file in the first; if I do :sh while editing the second view, the whole session pauses and a bash shell is opened, but I'm not able to edit the file and use the shell at the same time..
