I was rather late to the party in terms of realising that you can quickly comment and uncomment lines or blocks of text in the Enhanced Editor (or Enterprise Guide editor). Simply clicking ctrl-/ will insert /* at the beginning and */ at the end of each selected line. And it took me even longer to figure out that shift-ctrl-/ removes comments.
I'm sure there are many of these keyboard commands but I've never found them listed. Does anybody know where these are all listed? [See the subsequent comments for responses to my question]
