Something is crazy, but would that work?

Is it somehow possible in minecraft. Store a teleportation on a button? That means if I now sit in Mc at home and think that it would be great to visit the desert, I can help myself with a button. I take "L" then teleport to the place? Save the teleportation coordinate on any key. Stop as running forward is stored on "w"

Of course its possible. But only with a command or mod… Must be programmed somehow.

I don't think it's in Vanilla, but you can save it in a book.

With plugins you can do it so that if you enter the command / desert, you will be teleported there

Get the Warp Book Mod. It's nothing with a button, but you can also use it to teleport to coordinates that you right-click with a warp page. Then you can give these coordinates a name and put the warp page in the book and you can then teleport to these coordinates.

With LabyMod you can too. But you need the desert coordinators and you have to be able to enter commands. Then you can specify which button to execute which command. However, Labymod is not available in all versions and is then no longer a Vanilla mc.
