Add left/right keyboard shortcuts to Gallery expanded view

[misaugstad]

Brief description of problem/feature

When the expanded view is open, I think that we should have the following keyboard shortcuts at a minimum:

• Validate agree: A and Y
• Validate disagree: D and N
• Validate unsure: U
• Go to previous label: left arrow key
• Go to next label: right arrow key

Yes! :)

Hi! I was gonna give this shot until I realized I don't have any labels to validate in my DB. Does anyone know if there's a way to add/simulate labels in a dev environment with a DB that has its PII scrubbed?

(Or I might just be misunderstanding when the labels get added to the DB after the exploration phase. Please forgive my ignorance!)

Edit:

It seems my labels are showing up in the gallery of the dev environment but for some reason the validate page doesn't load anything. I get this error in the console:

TypeError: Cannot read properties of undefined (reading 'labels_validated')

I think that you probably just need to add even more labels for Validate to work! And you also need to add labels with a different account than the account you use to validate the labels. I think that you can see your own labels in Gallery, but not Validate

Good to know if I ever need to work on the validate page! My apologies for clogging up this thread earlier.
