As noted by @Trendfischer in his comment, the current behavior of vim is not (anymore?) to empty the register on the first press of
Now, if you picked the wrong register, here is what you can do:
- do not quit the recording mode (for now),
- create an empty line,
- paste the register you are overwriting (if you're recording in the
q register, it's
- now quit the recording mode (
- select the line you pasted above (without end of line mark:
0v$h; don't use
- yank it in the register you have overwritten (
"qy if you're using the
q register; again: don't use the line wise copy
- now you have your old macro back in the register and you can restart the recording of your new macro in the correct register.
Of course, with a bit of effort, you can rescue both the old and the new macro (but you have to start the process before pressing the second time the
q): just paste what you have recorded and yank in the "new"/"right" register.
