Hi! That's a good question and it's definitely inconvenient if the choice shortcuts interfere with the label shortcuts, or vice versa.
One option would be to just re-map the choice keys to something else – you can do that by defining custom shortcuts for "1", "2" and so on, corresponding to the option index: https://prodi.gy/docs/api-web-app#actions-custom-labels So you could make the choice key 1 something like "shift+alt+1". Alternatively, you could also define custom shortcuts for the individual labels in ner_manual, like P for PERSON etc. This can be helful if you're mostly working with the same label set and there's an obvious mapping that's easy to learn for the annotator and maybe even more intuitive than the numbers
