Apologies if this has been raised before but it would be nice in raw squigs mode if we could backtrack just one stroke, rather than erase the whole character and start again.

This can be done with the keyboard short-cut 'z'.

All the available keyboard shortcuts are listed in the FAQ, too (I know it's not obvious to look there for this question, but there is some good stuff).

I wonder what the equivalent of RTFM is in Chinese? :-)

Many thanks.

Well, NCIKU is very boring
