I’m trying to set leader key to space and set some keybindings with it.
I googled and searched this forum a lot today and I can’t find a single example of setting the leader key. Can anybody help me with it? Thank you.

I unmapped space in my .obsidian.vimrc with unmap <Space>. Now what? How to map space as leader or create key chord with it? I tried adding this to my .obsidian.vimrc:

exmap openGraph obcommand graph:open
nmap <leader>og openGraph
nmap <Space>og openGraph
But pressing <Space> o g in normal mode doesn’t display graph (it only creates new line as if I pressed only o). What am I missing? When I run manually :openGraph it works as it should.
              
Thank you very much, it works now!
It works when I use Space directly like this:

nmap <Space>og :openGraph
Do you know if it is actually possible to set space as leader key and use <leader> notation in my .obsidian.vimrc? Like this:

nmap <leader>og :openGraph

Sorry I haven’t tried it.
