This refers to the simple Wacko rule that all formatting tags (with the sole exception of list items) use the same character twice as a tag to open and close special formatting. For example...

//this would make text italic//
**this makes it bold**
^^this is superscript^^
??this adds a red emphasis??
>>this text is centered<<

See Wacko Formatting for more examples. Hopefully remembering this rule makes formatting somewhat easier!

=) this to somehow describe so that there would be the time. Its essence in the fact that the majority of the methods of Wacko- marking is accomplished by the different symbols, repeated twice. Concluding text into the dual nontext symbols, it is possible with the great probability to assume that this somehow will influence its exterior view.

Well and, of course, majority is limited by the end of the line and must close fit closely to the marked text. But the few, that unconfined by the end of the line
(this deletion and color isolations) nevertheless requires that the text close would touch to them.

I.e. thus__must to operate __, and  thus – no.
