-*** TODO Comment/Uncomment region
+*** Comment/Uncomment region
+
+    There is a cool function in emacs wich is =commend-dwim= (bounded
+    to =M-;=. This adds a comment at the right place (at the end of
+    the line, up the method, etc..
+
+    Something I'm really use to, with IntelliJ or Eclipse, is being
+    able to quickly comment a line or a region with simple
+    keystroke. If nothing is selected, it comments the current line,
+    if there is a selection, it comments the line selected (even if
+    the selection doesn't start at the beginning of line. Let's bind
+    it to =C-/=.

     I read an intersting article about [[https://medium.com/p/3a6db2743a1e/][how to make syntax highlighting more useful]]
     and I really like the concept. And guess what, there's a mode for that.
