For blank lines, if you don't use something from markdown, you can use shift-space + ALT+255 for a space character which would look like this:
<-There it is!
New line.
Which on our site would create that line-break you're looking for!
Aahh, yes, this makes sense now, thanks for the pointer! However, the shift-space + ALT+255 doesn't work, probably a windows-only command eh? Also tried the trailing space trick; "When you do want to insert a
break tag using Markdown, you end a line with two or more spaces, then type return.", to no avail. I'll keep looking, but to be honest it's truly not all that important, just more of a nuisance.
It's not all one command. Actually you don't need to shift either. So do this:
First line [hit enter]
[Alt+255] [hit enter]
Second line.
Ok your post helped me figured out my issue;
Alt+# changes browser tabs in linux, Alt-codes are Windows-only. For Linux GTK+ apps, like FF and Chromium, Ctrl+Shift+0U00A0 works just the same.
Thanks again BetMoose!
