A short example: While writing text I mistype an "f" (Screenshot 1) and want to undo it using C-z. The result is a missing rectangle selection and the last line having still an "f" (Screenshot 2).
abcdf abcd
abcdf --> abcd
abcdf abcdf
Instead I would like to keep the rectangle-selection and have no "f" remaining to continue typing.
abcdf abcd
abcdf --> abcd
abcdf abcd
Any suggestions? Thanks in advance!
