Mac Terminal: Delete a word at time

1. Select "Preferences..." from the Menu "Terminal"
2. go into "Settings" and select your default window configuration, go into the tab "Keyboard"
3. Have a look at all keybindings, (eg. forward delete is bound to \033[3~ ) and note you can change them by double clicking (thats easier to use than bind in your ~/.bash_profile).

If you choose to use ⌥ as meta-key, ⌥+backspace will work immediately, though this setup might break special characters you can only input by pressing ⌥ together with them (depending on your keyboard layout). If you don´t use that, you can delete by pressing esc and than backspace.

For forward-deleting a whole word, use either ⌥+D or esc and than D.

According to https://stackoverflow.com/questions/11676026/macvim-shell-sh-only-displays-character-codes-escape-sequences the initial ?1034h characters are the colour codes I've set up in my .bashrc.

When calling echo $TERM from macvim the result is dumb. It looks like the terminal is unable to interpret certain escape sequences.

Details on how to adjust the .bashrc to accommodate (taken from https://stackoverflow.com/a/11676355/783836):

If you would like to use a color prompt on the command line, but not in MacVim you can fix this in ~/.bashrc by setting PS1 differently when inside vim (from [here][1])

if [ $VIM ]; then
        export PS1='\h:\w\$ '
