`<home>` acts like `v<home>`

Pressing `<home>` or `<end>` should just move the selection.  Instead it widens from the current position to the beginning or end of the line.

In **Helix**:

`ihello world<esc><home>d` -> `ello world`

In **Dance - Helix**:

`ihello world<esc><home>d` -> empty buffer

I think I prefer the current behavior, but it doesn't correspond with helix's behavior, so I guess it's a bug.
