🧵 Voice Control/Shortcuts/iOS automation discoveries…
You can speak keyboard shortcuts to access functionality that isn't exposed easily by voice, or Shortcut actions. For example: increasing or decreasing the text size in Safari ("press command plus key" / "press command minus key"), quitting apps on iPadOS ("press command W key")
It seems to be limited by what the operating system itself supports, which is logical. So you can quit and switch apps (command–tab) on iPadOS but not iOS.
A couple of useful shortcuts in messages: cmd-e to edit your last message, cmd-t followed by 1-6 to send a tapback. (these work on all three platforms, including macOS.)
When dictating, it looks like the "that" used in such commands like "put quotes around that", "put parentheses around that" refers to the last uttered insertion by default if you don't have a selection. This provides a useful way to insert a quote or parenthetical clause more ergonomically, if you can say it all in one go.
