map the _ key to move the line up

[cyboman]

I have a - key mapped to move the line down. Here it is
map - ddp

I want to have a command opposite to it, _ to move the line up.
I tried map _ ddkP but it doesn't work. If I'm on the last line of text it will move the text two lines up and if I'm on the first line it simply deletes the lines, which makes sense why.

I know this is a simple task for most of you, but I have never fiddled with Vim mappings. I would appreciate if anyone could help me out.

Thanks.

Try kddp instead. This should work correctly even on the last line. On
the first line it will beep, and it may (or it may not) move the line
down instead. I haven't checked, but I think that on the first line it
will do nothing, which makes sense (you can't move the first line up,
can you?)


Best regards,
Tony.

Thanks Tony it worked, but I also added a k to the command so I could move one line up.

nnoremap _ kddpk

Try fiddling with searching the list. If you had read a recent thread titled “move a range of text to address”, you'd see that this is [probably] the preferred solution:

nnoremap _ :m-2<cr>
nnoremap - :m+<cr>
