OK, very new to Atom. We have installed it to a debian 8.4 system using:
wget https://atom.io/download/deb -O atom.deb
$ sudo dpkg -i atom.deb
On a mac, using Xquartz, I run an ssh -X terminal and bring up Atom on the Mac screen. And the e-key is backspace! If I used the keybinding resolver it says the e-key is bound to core:backspace body and a file ending in linux.cson. Of course, in the file core:backspace says it is bound to backspace. Looks like a terminal issue but the terminal works fine, emacs through the terminal works fine, but atom does this odd binding.
