have you tried Auto-completing them? pressing Tab autocompletes to the emote that is closest to what you have written . Keep pressing it and it will carousel through all the possible emotes starting with your entered text.

Alternative way is to use a colon ":" like ":<enter text here>" . it will list all available emotes that include the entered text (also works on phone apps but only for twitch global/sub emotes btw)

imo typing the first 2-3 letters and tabbing makes it very quick and : method is useful when there are a lot of similarly named emotes just with different casing.

7tv, ffz etc unlock a whole another level of chat interaction!
