A lot of text for a little map, isn't it? ;-)<p>Usually, I avoid remapping for insert mode, because
- typing ';' will pause for a while in case a key is pressed that triggers a mapping
- typing the mapping when you literally mean it is often surprising.<p>Instead, I use Ctrl+[ to escape from insert mode. Staying on the home row does not seem that important if you've just finished writing several sentences.
