Alt + 2 gets you 2. If you press 2 by itself, then you get tab.
A similar thing with 3. If you press 3 and release it, you get 3. If you hold 3 and press another key k, then you get Ctrl+k.
This works by using the "to_if_alone" feature in karabiner. e.g. https://karabiner-elements.pqrs.org/docs/json/typical-comple...
