Also, some tools have plugins to provide vim controls for them.
I know at least and use these:
- SublimeText (https://github.com/NeoVintageous/NeoVintageous)
- Firefox (https://addons.mozilla.org/en-US/firefox/addon/vimium-ff)
There are probably more...
You should just have received a text with a number on it, could you post that as well please?
