Being able to delete large blocks of text in a single bound is all very well and good, but what if you mistakenly delete 53 lines that you need? There's a way to recover any of your past nine deletions, because they're saved in numbered buffers. The last delete is saved in buffer 1, the second-to-last in buffer 2, and so on.
To recover a deletion, type <"> (the
double quote character), identify the buffered text by number, then give the
put command. To recover your second-to-last deletion
from buffer 2, type the following:
"2p
The deletion in buffer 2 is placed on the line below the cursor.
If you're not sure which buffer contains
the deletion you want to restore, you don't have to keep typing <">
n
p over and over again. If you use the
repeat
command (.) with p after u (undo), it
automatically increments the buffer number. As a result, you can search through
the numbered buffers as follows:
"1pu.u.u etc.to put the contents of each succeeding buffer in the file one after the other.
Each time you type u, the restored text is
removed; when you type a dot (.), the contents of the next
buffer is restored to your file. Keep typing u and . until you've recovered the text you're looking
for.
