Sometime you see an unlucky wording or just a typo that is not corrected by the spell checker just after you press <Enter>.
It would be useful to be possible to rectify this by typing a new message with a special syntax.
Probably the vim substitute command will be just enough.
For example you type:
You are stupid.
but you just realize that actually you wanted to say is:
You are the smartest person.
The only thing that you do is just type:
s/stupid/the smartest person
and the previous line is ameliorated.
The IM-clients that doesn't support this feature will simply display the line as it is, and the partner probably will understand what is meant anyway.
Some options could also be added:
- the replace operation limited to the last 3 send messages.
- the new text highlighted for 2 sec. so that the discussion partner see that something changed.
