Normally when we discuss cut, copy, and paste, we talk about putting text on a clipboard. In Vim's terminology, we don't deal with a clipboard but instead with register.

Transposing Characters

x

cuts the character under the cursor, placing a copy of it in the unnamed register.

p

pastes the contents of the unnamed register after the cursor position.

xp

Transpose the next two characters.

Transposing Lines

dd

cuts the current line, placing it into the unnamed register.

p

pastes the contents of the unnamed register after the current line.

ddp

Transpose the order of this line and its successor.

Duplicating Lines

yyp

duplicates current line. Does a line-wise copy and paste.

Oops! I Clobbered My Yank

P

paste the contents of our unnamed register in front of the cursor.

diw

in this case, overwrite the contents of the unnamed register.
