Keyboard shortcut for "Ctrl + Arrow" to select a message to reply to

### Your use case

#### What would you like to do?

Reply to messages without having to use a mouse

#### Why would you like to do it?

To use the app more quickly, as if somebody currently wants to use the reply feature, from my understanding they are forced to use a mouse.

#### How would you like to achieve it?

When the user hits "Ctrl + Up Arrow" for example, the latest message will be selected for replying.

The user can use the arrow keys while holding control to move the selection up and down to reply to different messages.

The user's own messages will be treated the same as others' messages when selecting to be replied to through this feature.

(The exact shortcut could be user selectable, toggleable, or just something different but I thought "Ctrl + Arrow" made sense.)

### Have you considered any alternatives?
