add navigation by ArrowUp/ArrowDown

[adirtyshame]

i just saw your post on dev.to and found your project interesting.
by reading through the code i found your "todo" regarding navigation by arrow keys.
my pull request does the following:

• the input field and the emoji buttons are getting a tabindex attribute
• the seach function uses filter() instead of if
• i remember the length of the filtered emojis (line 39)
• i added a keydown listener, where i test for ArrowUp or ArrowDown
  cheers

Going ahead with the merge!

You're welcome :-) Would it be ok when I add some kaomojis to the list? Virej Dasani ***@***.***> schrieb am Di., 25. Mai 2021, 15:24:

Kaomoji support would be really cool. Go for it!
