This may sound convoluted, but you could create a custom command in Keyboard->Shortcuts (Add New -> Command or Script) that uses ydotool (uses a service) that is basically ydotool type "|>" and then create a shortcut of Ctrl+$ for it.
Edit: I just tried this, it seems like custom shortcuts aren't working?
Mine backs up my text messages, but I would prefer to backup my app data, authenticators, wallpaper, themes, games, etc., not every app is a shitty front-end to a website.
That just might be crazy enough to work, perhaps the tunnel can be made of scaffolding, so people can get some of that sweet sunlight while they go through it?
I mean, 1 and 4/5 an inch is pretty close to 45mm...
