Hint button or pop-up for cloze speed

Add a hot button on a toolbar that makes a hint.

Shows up only when highlighting or having the cursor in a cloze.

or

Add a small pop-up button when hovering over a cloze with no hint. Adds it.

Why? First of all, because at times fast-typing /hint has a lag and the whole rem has to be corrected

Why? 2 steps instead of 3

1. I highlight by shift+{

2. I have to leave the highlight (bc a slash would replace it)

3. type /hint

For whom? For making lots of clozes fast and later going over them to add hints
