IT notes

🔗Quote/unquote words:

ciw'Ctrl+r"'

or

ciw '' Esc p

p paste after the cursor, P will paste before the cursor.

🔗Search matches (gn with the dot command)

Suppose that we have a document containing several occurrences of the word ‘Normal’ and we’d like to change each occurrence to ‘Visual’. We can run /Normal to search for the word ‘Normal’, then type cgnVisual<Esc> to change the next match to the word ‘Visual’ and by pressing . it will change the next match. No need to use n. (http://vimcasts.org/episodes/operating-on-search-matches-using-gn/)

🔗Habit breaking

Moving your Vim cursor around using the arrow keys is a bad habit, and like many bad habits it’s a difficult one to break! Putting these lines into your vimrc can help:

nnoremap <up>    <nop>
nnoremap <down>  <nop>
nnoremap <left>  <nop>
nnoremap <right> <nop>
inoremap <up>    <nop>
inoremap <down>  <nop>
inoremap <left>  <nop>
inoremap <right> <nop>

This snippet causes each of the arrow keys to execute no operation, or in other words: it disables them.

🔗Traversing test in insert mode

While in insert mode, use Ctrl-O to go to normal mode for just one command

CTRL-o h  move cursor left
CTRL-o l  move cursor right
CTRL-o j  move cursor down
CTRL-o k  move cursor up

CTRL-w    delete word to the left of cursor
CTRL-o D  delete everything to the right of cursor
CTRL-u    delete everything to the left of cursor
CTRL-h    backspace/delete
CTRL-j    insert newline (easier than reaching for the return key)
CTRL-t    indent current line
CTRL-d    un-indent current line
