Copy, delete, then paste in Vim

Solution 1:

Take a look at :h copy-move. The default yank or delete goes into a place called a register (a register named "). If you need to delete some text before you paste, you need to avoid overwriting register x, as you've discovered. Fortunately, you can use any other letter or number to name a different register.

• "ayy (yank a line into register a)
• x, dd, etc. (delete some text into the unnamed register, ")
• "ap (paste the text from register a)

Solution 2:

If the problem is that you merely need to replace some text with some text2, then, just highlight and yank text2. Then highlight text and press p or P to paste text2 in place of text.

Edit: note that p pastes text after the cursor and P before the cursor.
