@Andreas_Hegenberg This type of action sequence no longer works. I have tried this in three different apps. Here is an example with TextEdit
The macro above should open the menu and keep it open. Like this
Thanks for taking a look!
Ok, solved with a workaround. But there is a bug here.
I‘ll have a look, which version are you on?
4.622 and Ventura 13.2.1. Thanks.
Mhh, it seems to work as you described here:
Can you describe what it does in your case? Does it not open the menu at all? What kind of workaround did you find?
Very strange. Did you use the same actions as I did?
My workaround is to "enter" the menu with "arrow down" and not to use the action insert custom text.
Yes I used the exact same sequence 
Are you using a keyboard shortcut to trigger this?
Yes, fn + letter.
Well, the main thing is that there is a workaround. But it is strange. Actually, it always worked well.
I think I can see the issue in some of the apps (but not textedit in my case). It somehow seems to be related to the delay - without delay it always seems to work here.
I'll check what is happening there
//edit: ah no, the delay is only problematic for menu items inside of BTT, but that is a kind of expected technical limitation
Haha, you're right. It also works without a delay. I added the delay automatically because it takes a certain amount of time to open the menu. But the down arrow shouldn't really be necessary and for certain menu names that require more than just one letter, the "type custom text" action is more practical.
