Joop, please nb: this forum's HTML formatters do not use '\' but rather
'/'.
Seems you have much of former, hence, misformatted.
Also, there are some potential *shortcuts* in termination, which can be exploited
or not: e.g., I've found (the accidental way) that an '[/i]' closure will also close
underlining (so some few keystrokes can be spared). There are likely other cases,
and I think that closing a quote will terminate within-quoted text formatters.
BTW, I've
not usually used the clickable formatting buttons (which seem to
just spit out some formatters between which one must then move to write), but
type them. If you're clicking and getting the backslashes, then ... hmmmm !
