This plugin for Obsidian allows you to quickly search for and add emojis to your editor.
After enabling the plugin, you'll find a new hot key setting called Emoji Toolbar: Open emoji picker
. Set this to whatever you like. Once clicked it will allow you to search through a list of emojis.
Start typing a word to filter through the list. You can insert the emoji into the editor by either clicking on it, or use the arrow keys and then press enter to insert the emoji.
