@grahamlangford @fungairino I think it would make sense to split this into 2 separate issues. I created @pixies/test/text-snippets and spent a little time trying to get keyboard controls to work on https://pbx.vercel.app/advanced-fields/. Even for the basic input, it's non-trivial. E.g., know which delays, etc. are required to toggle the menu. And using .press("Tab") to complete, it was having issues where the \s snippet query wouldn't be cleared

I ran into some of the issues Todd described here, but I was able to write a very simple test without the keyboard controls (using just clicks to select the snippet).

I'd say we create a follow-up for further e2e testing using arrow controls and searching if needed after this PR closes out the issue.

I also suspect the difficulty in using the keyboard controls in e2e tests might be indicative of some buggy behavior that we might need to dig deeper into.
