Bram,
one of my annoyances with vim currently is, that when using n/N for
searching the direction depends on the previous search command. But I
usually forget if I initially used / or ? and then my brain gets stuck
whether I need to press n to search backwards or N. (e.g. I start a
search backwards using '?' and want to go further upwards and press
routinely 'N', but this moves back downwards again).
I find it easier to know that n searches downwards while N searches
upwards, since I usually only know whether I want to go further down or
up, so I can reliably hit n to go further down and N to go further up to
the next match.
This is what the attached patch enables, by adding the new flag 'N' to
the 'cpo' setting.
regards,
Christian
