Dear vim-riv,
It seems that for the keyboard where the number require to use the shift key like the french or Belgian keyboard the mapping proposed for title or section is not working on Neovim (it is working well on gVim)
To make it working I had to change the cmd.vim and replace
'maps' : ['s0']
...
'maps' : ['s6']
by
'maps" : ['s<S-0>']
...
'maps" : ['s<S-6>']
Best regards,
Vivian.
