In Hipchat clent, after perform comand, (simular text editor vim) :
s/to_be_changed/result last message changed, it's working.

But always type s// to change last message is not comfortable.
Is it possible to make a changes in last sent message changes in friendly way?
for example :
1.clicking last message,
2.make changes
3 get attribute changed (for example skype) in this message

Thanks for attention
