Hello, I read this topic.
https://forums.opera.com/topic/29487/remove-ctrl-shift-v-macro
The same problem happened in my mac pc, so I access to
opera://settings/keyboardShortcuts
and changed the setting.
As a result, Google automatic search has successfully stopped.
But, Google Sheet macro for "Paste with no formatting" still doesn't work.
I press CTRL+SHIFT+V on Google Sheet, but nothing happens.
What's wrong with my opera browser??
