When emoji popup trggered, three keys - Tab, Enter, Right - complete current highlighted emoji.
How about using Right key as 'expand selectable emoji`?
I know I can select any emoji if I guess first character for the emoji. But as not native english speaker, sometimes quite hard imagine proper word for certain image that popped up in my head. Or just wanna looking for what emoji are available.
- ‘:’ trigger default 5 emoji
- ‘Right’ expand 5 to n (20? 30?)
- ‘Right’ change default 5 emoji popup to category select popup.
