What I didnt make clear in my video is that I dont hold the Ctrl+Enter. 
Once the menu is open,  I am using the arrow keys and Enter independently. 

So this is different to what you say

When you release Ctrl you can navigate the list but it impossible to place any item because the lists disappears when you press Ctrl again.

Perhaps you can try reset Studio given you posted this against CU10 and presumably it was working correctly before.

Instructions on how to reset & repair Studio can be found here.

Let me know how you get on

Hi Lydia,

Thank you for your answer. What I found reading documentation is that items from the pop-up list can be placed either using Enter or Tab key. So while the Enter key cannot be used anymore (at least on my machines), I can still use the TAB key, which works for now. It took some time to get used to, but after a few hours you adjust.
