Hi user_5359,
Errors are corected.
It's comes with Potlach's short cuts.
If you type
b<return>w<return>
you get the tags barrier=wall
which is extremly quick.
But ... if you type too quickly (or your PC is too slow)
you get the error you checked.
Thanks for your attention.
Best regards,
Daniel (DF45)
