How do I get Ctrl-o/i working?

[dseravalli]

I built the plugin from main and am trying to get the ctrl-o/i keymaps in the example working. Yanking to clipboard is working so I know in general the plugin is set up correctly.

set clipboard=unnamed

exmap back obcommand app:go-back
nmap <C-o> :back<CR>
exmap forward obcommand app:go-forward
nmap <C-i> :forward<CR>
