Add option for fast adding words like on https://app.lokalise.com

[Fjoerfoks]

I am currently also localizing on https://app.lokalise.com and what I really like is the feature to add words quickly like T9 on mobile with automatic suggested words in a submenu.

Might be a useful feature to consider for Pontoon.

Hey @Fjoerfoks, could you say a bit more about the feature or link to documentation or some other online resource?

We've been thinking about implementing autocomplete feature, which would adapt based on what you've already written. I wonder if this feature is similar.
