――In addition to the editor you usually use, you may use vim several times a day or a month.
――Therefore, there was no problem in the following situations.
--Use is only for ** basic operation ** (move / save / end).
--Therefore, a few lines or a blank .vimrc.
--Complicated operations are manual input or copy.
――This time, in order to further reduce the finger burden of such basic operations, we will describe the settings of Vim's ** Leader ** function.
--Shows a description of the resulting .vimrc.
--With the following settings, basic operations (move / save / end) can also be used with "** Space + various keys **".
"Set leader to space
let mapleader = "\<Space>"
""Space key+Key operation mapping such as "various keys"
inoremap <Leader>jj <Esc> "ESC key
nnoremap <Leader>w :w<CR> "Save
nnoremap <Leader>q :q<CR> "End
noremap <Leader>a myggVG$ "Select all(normal)
inoremap <Leader>a <Esc>myggVG$ "Select all(insert)
nnoremap <silent> <Leader>vr :new ~/.vimrc<CR> " .open vimrc
nnoremap <silent> <Leader>r :source ~/.vimrc<CR> " .loading vimrc
noremap <Leader><Leader> <C-w>w "Move window
map <leader>n :call RenameFile()<cr> "Rename the file being edited
"Rename function definition
function! RenameCurrentFile()
let old = expand('%')
let new = input('New file name: ', old , 'file')
if new != '' && new != old

exec ':silent !rm ' . old

-Leader is a special character string and setting that can be assigned multiple key operations. ――In other words, you can create your own key mapping (shortcut) on Vim.
――When setting, I was conscious of the following. --Starting from the space key. -Try various keys such as "," and select the one that suits you best. --High frequency only setting --Identify frequently used operations. --Do not set more than necessary --Avoid increasing the number too much, as key collisions will occur. --Short standard operations are not basic settings.
--The main contents set in the above result are as follows. (** * Set by focusing on basic operations *) --space key + jj: ESC key --space key + w: save --space key + q: Finish --space key + a: Select all --space key + n: Rename the file being edited - Separate function definition
