It seems that your mapping is not being interpreted by Vim, so it only sees the Ctrl-c, which by default aborts the current action, then the replace command r
(see :help r
) followed by its "argument".
You could check if the mapping is defined with :map <c-c>
.
If it is correctly defined it may be that your terminal is handling the Ctrl-c directly and not passing it to Vim, as stated in Vim FAQ 20.5 - Why does mapping the key not work?. In this case you could follow the instructions on Vim FAQ 20.4 - I am not able to create a mapping for the key. What is wrong?, in special:
1) First make sure, the key is passed correctly to Vim. To determine if
this is the case, put Vim in Insert mode and then hit Ctrl-V (or
Ctrl-Q if your Ctrl-V is remapped to the paste operation (e.g. on
Windows if you are using the mswin.vim script file) followed by your
key.
If nothing appears in the buffer (and assuming that you have
'showcmd' on, ^V remains displayed near the bottom right of the Vim
screen), then Vim doesn't get your key correctly and there is nothing
to be done, other than selecting a different key for your mapping or
using GVim, which should recognise the key correctly.
