Append keys to an earlier recording in vim

Question

I know what recording in vim is.

Let's say I have already a recording on a register and I'm missing some more keys that I want to add to that sequence. Is there a way to append these keys to an earlier recording in vim?

Answer 1

Using an uppercase letter will append to a register, so qA would continue recording the @a macro.

From :help q:

q{0-9a-zA-Z"}       Record typed characters into register {0-9a-zA-Z"}
                    (uppercase to append).

Note: this works for everything related to registers, so "Ayw would also append the next word to register "a.
