Hi,
someone asked for a "delete backwards to a period"-macro, meaning to delete the beginning of a "sentence" from the cursor.
Here is my trial. The only thing which doesn't work is to delete the beginning of the first sentence of a document. Here one can press ⇧+↖ and ⌫. (Or is there someone who has an idea to modify the regexp ;)
If one would replace in both macros (DelToPeriod, DelBackToPeriod) the '.' by [[:punct:]], one could delete to any punctuation mark, declared in the Oniguruma grammar, followed by a space or newline.
Cheers,
Hans
