You claim that you forget Vim keybindings, but then you have this on your about page:

   email: echo soaper.:.disroot.:.org | sed 's/.:./@/; s/.:././'

We all have limited capacity to learn stuff. If I didn't already know Vim, there's very little chance I'd have the motivation/time/energy to learn it for the first time now.

What’s that have to do with Vim keybindings in particular?

[behnamoh]

I was just saying that if one can remember sed syntax, Vim's should be easy to follow.

You don't need to memorize the syntax to have a script.

[wharvle]

No joke: I wouldn’t have a programming career if remembering syntax were a requirement.

The author might just have copied that sed expression form someone else.

Or looked it up once and probably now forgotten it.

Also regex expressions are not vi expresions and have wider applications so author might use them regularly.

So nothing here suggest that the author can remember vi.
