How to find shortcut keys (⌘⌥⇧⌃) in Unicode popover?

• ⌘: type "place of interest" (this took me a while to figure out, had tried "point of.." and "attraction")
• ⌥ just type "option"!
• ⇧: type "upwards white arrow" (bonus: ⇪)
• ⌃: type "up arrowhead" (it's not the standard caret)

Bonus:

• ⌫ & ⌦: type "erase"

Edit: Though this method would not help for the smaller 'emoji popover' [see comments below] I'll leave it here in case future Googlers might find it useful.

To save having to remember all their names every time, just add that category to your Character Sidebar.

At the top left, click the gear icon [it looks greyed out until you open the list, but it does work]

Click the reveal error on Symbols & add Technical Symbols.

All the standard Apple keyboard symbols are in the first few lines.

Bonus - if you also add Unicode [In Code Tables, way down the bottom] to the sidebar it adds the Unicode references to the preview on the right too.

Note:
it used to be called the 'Character Viewer', now it rather limply styles itself as 'Emoji & Symbols'... but whoever thought up that snappy name forgot to change the actual window title :/
