What are the must have vim commands to place in my vimrc file for general editing [duplicate]

What is in your .vimrc?

I am fairly confident with vim having used it on and off for the pa开发者_运维问答st 3 years but I keep finding new simple suggestions for my vimrc for general editing which, after I use them seem blatantly obvious.

An example being:

noremap p "+p
noremap y "+y

For OS clipboard use (on my linux box anyway)

Another example being:

imap jj <ESC>

So in an attempt to collect together a definitive set of simple vimrc entries I will ask the questions, which do you find most useful?

Edit:

I am looking for the most basic vim commands, not functions and stringed commands

This will save you a lot of pinky strain over the years

nnoremap ; :

This remaps ; to :, as it is a relatively unused key and you don't have to press shift for the :. The : still works, just in case you still press shift from muscle memory.

Personally, I've also found these to be helpful:

1) Use first person shooter (FPS) games' movement keys for window movements (not a good idea if you use A or D often. I don't.)

map <W> <C-w><Up>
map <S> <C-w><Down>
map <A> <C-w><Left>
map <D> <C-w><Right>

2) Use <space> as a leader

nnoremap <space> <Nop>
let mapleader = " "

3) Disable middle mouse, especially on a mac, where inadvertently using the mouse (to switch applications) pastes content if middle click is accidentally pressed

map <MiddleMouse> <Nop>
imap <MiddleMouse> <Nop>

4) Movement between tabs (kind of similar to Firefox)

map <T> :tabnew<Space>
map <Q> :tabclose<cr>
map <Leader>[ gT
map <Leader>] gt

I forgot to add that for the above, I use it as T <filename><enter>, which is a nice and quick way of opening a file in the current directory in a new tab.
