Vim is full of various commands, which are assigned to almost all keys on the keyboard.
But this causes a problem: Which commands can we use for our own commands
,
without interfering with existing ones? And at this moment, the <Leader>
key comes into play.
Think about <Leader>-key
like a namespace for any user-defined commands.
You can assign any command to a mapping with a leading <Leader>
and you can be fully
confident that your mapping won‘t break anything.
By default your <leader>
is \
, backslash. You can check it with:
:echo mapleader
If this gives you an E121: Undefined variable: mapleader
,
it means it‘s set to the default of \
. If it gives you something else, then it‘s that ??
You can easily remap it. I mapped it to the space-bar:
:let mapleader = "\<Space>"
Note that the value of mapleader
is used at the moment the mapping is defined. So this example:
let mapleader = ","
nnoremap <Leader>a :echo "Hey there ,"<CR>
let mapleader = "\<Space>"
nnoremap <Leader>a :echo "Hey there space"<CR>
Will produce two mappings: ,a
and <Space>a
.
This means that the current value of mapleader
is not necessarily the
value that was used to define your mappings!
In addition, there‘s the maplocalleader
, which is the same as mapleader
,
except that it‘s used by <LocalLeader>
and that it‘s local to the current buffer.
More information about <Leader>
can be found in Vim‘s help with :help mapleader
.
