### Problem Description

It'd be great to be able to navigate within the FreeTube UI remotely, without using a mouse — e.g. using a TV remote control and/or a game controller.

### Proposed Solution

Support navigation via a TV remote control or a game controller.

### Alternatives Considered

Rather than supporting alternative inputs in the standard interface, there could be a separate "big screen" interface for just these inputs.

### Issue Labels
