Close "recent searches" when hitting ENTER, or something similar

Very simple thing: when I search in Deezer desktop app for MacOS open the "recent searches" box, which is great, but the only way I found to get rid of it (as it covers the part of the UI which allows me to filter by album/artist/etc.. is to click somewhere. I'd wish for a simpler way, with the computer keyboard, like pressing ENTER would close it.
