End shape tool with tool switch
Currently if you create a few curves/lines with the
shape tool and switch tools before hitting enter or
completing the path it will just go away.
I'm not sure where I picked up this habit, however in
some drawing tool or another this was my main method
for ending curves.
A more reasonable behavior would be to do the same
thing pressing the enter key does.
I'm assigning it to myself, because I'm the one who
cares and I can code. Posting it here for discussion
or if i give up and forget about it.
