## Select / extend mode
|
|
|

I'm still pondering whether to keep this mode or not. It changes movement
|
|
commands to extend the existing selection instead of replacing it.

|
|
|
> NOTE: It's a bit confusing at the moment because extend hasn't been
|
|
> implemented for all movement commands yet.
