I started recently to use Emacs and am learning the basic commands. So I haven't customized it in any way. Just installed it. But when I use de C-x Del command to kill to the beggining of the sentence, it open directory listing instead.
The command I want to use is backward-kill-sentence, and in help (C-h f) says it's bounded to C-x DEL. Anyone knows why it's calling this other function ? How do I make myself sure that the key bindings are the default ones ?
