In a game I'm making I wanted to add a feature where you can change the controls and I would find it alot easier with these 2 blocks.
First up a “when key (any) is pressed” would be useful so I know if they pressed anything. I could make the code to wait for any key to be pressed before changing the key.

<key [any v] pressed?>

Also a “last key press” could be useful with the same script, I would say wait until any key is pressed and set the control to that key.

(last key press)

A simplified version of the code I would use it in would look like this:

when I receive [change control v]
wait until <key [any v] pressed?>
set [control v] to (last key press)

These blocks you've suggested could be very useful in a bunch of different types of projects. Support!

key ,any> presssed

already exists.

Last key pressed can be worked around (Albeit it is clunky), and there is a turbowarp block for that, but I would like to see something like this.

Uhm…

key any press already exists.
And last key pressed may be a duplicate but I tried searching but ocular's down.

Then that's the duplicate I assume.
