You can use the new* Skype feature for doing this:
!! Preformatted text: Use two exclamation marks and a whitespace (<Space> or linebreak) as the first 3 characters of your message and paste your snippet after it. Example: This is (not) a kissing smiley! :*
You can also use these commands to turn this on or off:
/wikimarkup off // Text will not be converted. /wikimarkup on // Text will be converted.
Turning conversion off (e.g. with !!
) disables the following formatting features, among others:
* bold *
~ strikethrough ~
_ italic _
and it also displays URL without formatting them to clickable hyperlinks or displaying the site's thumbnail as an image.
* It's available in the latest version on Windows 8 & Windows 7 (Skype version 6.22.81.105 onwards).
