To bridge the gap of difficulty between multiple choice and typing exercises this script changes the box color (green/red) depending on whether the answer is correct so far and displays a keyboard of keys for the remaining characters to get to the correct answer.
I am sharing in case someone finds it useful and wants to build on it.

Great idea, thanks for sharing!
@lurkmoophy: what do you think, wouldn’t this be a great extension for the web app?
Nice, is this script supposed to be typed in the console when you inspect the code.
My pleasure, thanks! I improved it a little (for example, if the current_streak < 5, the first letter is colored green, there will be at least 7 keys even if the word is small)
$(document).ready(function() {
function main(first=false){
if(MEMRISE.garden.box.template === 'typing'){
var current_streak = streak();
if(current_streak < 10){
mark();
keyboard(first);
}else if(current_streak < 20){
mark();
}else{
empty();
}
}
}
function streak(){
return MEMRISE.garden.box.thinguser.current_streak;
}
//Events
MEMRISE.garden._events.start.push(() => {
$('body').on('.typing input', 'input', function(e) {
console.debug(e);
main();
});
$('body').on('select', function(e) {

MEMRISE.garden._events.activate.push(() => {

I use Tampermonkey (Firefox addon), which handles all the injection for you 
Thank you so much it is working now
