Ctrl-p is commonly equivalent with the up arrow - in the command line it gets the previous command and in an Emacs buffer it moves the cursor up a line. Within a Docker container however it is needed to type Ctrl-p twice before it actually executes, while with up arrow it works fine.
This has always happened (at least since Docker 1.3 that I remember) up to today 1.9. Is there any fix for this? It’s quite an inconvenience if you’re used to this shortcut instead of the up arrow.
Ctrl-n (down arrow) on the other hand works fine.
