Vim undo (delete) characters written by imap!

Question

in vim, is there a way to remove a block of text written by (no) remap or iab? for example let's say I have

inoremap xx \ hat {x}

in my .vimrc file, I want to be able to delete \ hat {x} with one keystroke (but not ^ w or dB .. I could have two consecutive iabs consisting of just text, so I need to be able to cut abababcdcdcd in the middle if cdcdcd is iab, say "cc")

any ideas?

Answer 1

Finally, a clean solution

inoremap xx ^Gu\hat{x}^Gu

(It's C-gover there)
