Automatically start in insert mode when inside the terminal

[dagadbm]

As above /\ also make it toggleable.

[dagadbm]

autocmd BufEnter term://* startinsert
autocmd BufLeave term://* stopinsert

This is what worked for me although I see a lot of people using
:au BufEnter * if &buftype == 'terminal' | :startinsert | endif
