Disable Safari's "Email This Page" shortcut
I have the same issue as this post: https://discussions.apple.com/thread/251230865
I want to be able to easily italicize something in Safari using the cmd+i shortcut. u works fine for underline, and b works fine for bold, but i opens the mail app.
Following the instructions above I added the Email This Page shortcut to something else, yet still when I click cmd+i it opens the mail app. Interestingly enough, on this Apple Community page it activates italics... but not on other sites I use: dndbeyond or reddit for example, where it still opens up Mail.
Why does it seem to selectively work here, but not elsewhere? And how can I disable this shortcut?
