Actually this is a good hint at how to do advanced commands in VI.
g/outahere/d
will globally find every line with outta here in it and delete that line.
Perhaps we need a gred command to delete all files with a word in them :-)
Actually makes me remember when I was only able to see two or three lines on
my Sun computer I switched from using vi to using ex. There were a couple
things that were difficult to do in ex blike joining two lines, but usually I
found I was less likely to lose the cursor in 30 lines of text, and could
usually get things done just as efficiently. I wonder, if we could take that
idea and pair it withBraille routing keys to make an efficient editor for
braille users.
I expect this would be easier to create on a android based notetaker than on a
Macintosh.
Any thoughts?
Best wishes,
Jonathan Cohn
