KB00027 - How to copy and paste as plain text with Stickies
When you copy cells from Excel or text from Internet Explorer, and paste into a sticky, text formatting will often get copied as well.
If you'd prefer to paste into a sticky as just the plain text, hold shift
as you paste.
Similarly, text in a sticky has formatting information, so if you'd prefer to just
copy it as plain, again hold shift
as you copy.
