The names for macOS keyboard meta-characters

You can insert a ⌘ character using the Character Viewer pop-up.

But the characters for macOS meta-keys like command and option have unusual names which makes them hard to find by searching. Their names are:

• ⌘ - “PLACE OF INTEREST”
• ⇧ - “UPWARDS WHITE ARROW”
• ⇪ - “UPWARDS WHITE ARROW FROM BAR”
• ⌃ - “UP ARROWHEAD”
