Totally pointless. Cmd + Ctrl + Space is the default key combo to bring up the character palette, you can then search for whatever character you want.
Oh, wow, I hadn’t realized the Character Viewer (the window opened by that shortcut) had gotten so much easier to use in more recent macOS versions – or did I never notice that top-right button that converts the floating palette into a popup near the cursor?
Opening the Character Viewer as a palette window keeps keyboard focus in the text field you are in, so it requires a lot of mouse usage to search for and to insert the character you want. I see that after toggling the Character Viewer to the popup mode (the default mode on macOS 10.15), the search field is focused after pressing ⌃⌘Space, the arrow keys select a character, and I can insert the selected character with Return. That’s much more convenient.
On newer Macs (at least the legend for it, it’s prob available or configurable), it’s just straight up bound to pressing fn.
Thanks for the comment. I am going to update the article with this information.
Sounds good. Sorry if I came across as harsh.
