i'm running Ubntu12.04 precise but I've seen this in other distributions too.

In the vi editor
vi --version
VIM - Vi IMproved 7.3

If in insert mode such as when correcting a word and using the change word (cw) command. I wish to change the first part of the word and delete the later part of a word. When I use the delete key to delete subsquent characters, it correctly deletes forward but also changes the last wanted character to uppercase. I then have to go back and invert the case. Its somewhat annoying.

Is the a cure.

Tried Googling this but its too obtuse for the search engine.

must be an ubuntu thing. ive seen some strange editing from vi under OSx, but never anything like you describe.

Just checked with Vim 7.2 and 7.3 (Slackware), nothing like you described.

Must be Ubuntu thing as lleb says.

Does your delete key work normally when editing commands at a command prompt?

What do you see at a command prompt if you type Ctrl+v (that's press Ctrl, keep it pressed and press v) and then press delete?

Do you have a ~/.inputrc file? If so, what's in it?

Which terminal emulator are you using? What is $TERM?

Are you using vi or vim? I find vi under debian based OS to be really messed up to use. I always install vim.

I've seen this with vi (vim-minimal in Fedora; vim-tiny in Ubuntu). It doesn't seem to happen with a full installation of vim

From the OP...

I am using vi not vim.
TERM is xterm
and there is no .inputrc file
The delete forward key works on the command line without changing the case

I installed vim and the problem doesn't present in vim so I guess my problem
is solved.

Thanks for your suggestions.

Now I am confused, in your original post you had this...

So you are invoking it with "vi" but that is probably a symlink to vim - or did I miss something?

Anyway, glad you got it working.
