I have set "settings > interface > extra results hotkey" for CTRL + # (where # is a digit) to "launch and stay open". Likewise CTRL + left click launches a the clicked match and keeps FARR open. I want the same functionality for CTRL + enter/return. I use enter/return all the time to launch the first match. Every now and then I want to launch that first match, or use the navkeys to move down the list of matches, and keep FARR open without using the digit keys. I prefer CTRL + enter since my hands always find those keys without looking. Not so for the digit keys. Maybe others with similarly wired hands will appreciate this feature too.
If this is already possible please help he set that up. Otherwise, consider this a feature request.
