Toggle selecting all deps

[V1RE]

Clear and concise description of the problem

Many times when working in a big monorepo I want to only select a few updates using interactive mode. This means I have to manually deselect the deps I want to exclude.

Suggested solution

I'd love to have a keybind to quickly toggle selecting all deps. Pnpm's interactive upgrade mode has similar functionality bound to a. If people are interested, I'd be willing to create a PR for this
