I seem to have something odd with either my Mac 10.6 terminal or my .vimrc.
When I type backspace on my laptop's keyboard, it only works when the cursor is at the end of the line. Trying to delete from within a line does nothing. MacVim operates normally. Google hasn't helped because I can't even figure out what to call this behavior.
All other backspace commands in my Terminal work as expected, so I am leaning towards it being Vim specific.
Here's the output of my ~/.vimrc 's mappings, I can't see anything that would make Vim in the terminal operate this way:
cflewis@coral-reef ~> egrep ".*map.*" ~/.vimrc "inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>" let mapleader = "," map Q gq nmap <silent> <leader>s :set nolist!<CR> " extended '%' mapping for if/then/else/end etc map <S-Insert> <MiddleMouse> map! <S-Insert> <MiddleMouse> nmap <silent> <C-N> :silent noh<CR> nmap <C-E> :b#<CR> nmap <C-P> :NERDTreeToggle<CR> nmap <leader>p :NERDTreeFind<CR> nmap <leader>/ :call NERDComment(0, "invert")<cr> vmap <leader>/ :call NERDComment(0, "invert")<cr> nmap <leader>t :TlistToggle<CR> nmap <leader>e :e **/ nmap <Leader>b :MiniBufExplorer<cr> nmap <Leader>sh :ConqueSplit bash<cr> nmap <Leader>r :ConqueSplit " map ,y to show the yankring nmap <leader>y :YRShow<cr> imap <silent> <Down> <C-o>gj imap <silent> <Up> <C-o>gk nmap <silent> <Down> gj nmap <silent> <Up> gk cmap w!! %!sudo tee > /dev/null % inoremap jj <Esc> nnoremap JJJJ <Nop> Any ideas would be appreciated. I tried flipping the delete key to send ^H or ^?, to no difference.

To fix “not working” backspace key in the insert mode permanently, add set backspace=indent,eol,start command to vi / vim configuration file in your $HOME directory.
This is due to the default setting for the 'backspace' option. Adding set backspace=indent,eol,start to your ~/. vimrc is the behavior that you probably want. Aha, that was it.
vi/vim editor FAQ: What is the vi/vim backspace key? In Vim, you delete the character under the cursor using the 'x' key while in command mode (which is the equivalent of a [delete] key), and to delete characters to the left of the cursor -- which is the equivalent of a vim backspace key -- use the capital letter 'X'.
In MacVim, you can use Command 'Left Arrow' and Command 'Right Arrow' to go to the beginning and end of line while being in edit mode.
Most likely, the "problem" you're seeing is that you can't delete anything that was not typed during your current insert mode session. This is due to the default setting for the 'backspace' option. Adding set backspace=indent,eol,start to your ~/.vimrc is the behavior that you probably want.

This is the only explicit backspace mapping I have in my config. I do not know if it will help for your problem, but it might be worth a try?
