I recently changed my Mail.app settings so that images in mail messages are not loaded automatically. Until the new privacy features in macOS Monterey roll out, I made this change to avoid some tracking by spammers (and mailer services). (You can find this setting in Mail > Preferences > Viewing)

However, I quickly grew tired of having to click the "Load remote content" (sic) button to display legit message properly. If there were a menu command for this (ahem, Apple) it would be simple to use a keyboard shortcut to accomplish this. Unfortunately, clicking is the only way to interact with this control.

When I searched the 'net for solutions, I found several complex AppleScript solutions to the problem. (You'll find them, too.) But these didn't appeal to me at all, so I turned to the excellent Keyboard Maestro instead. It turned out to be a stupidly simple problem to solve, as you can see in the one-step macro below.

Enjoy!
