e.g. Ctrl+Up/Ctrl+Down (I vaguely remember this one from ~1999 in another Basic editor ;) )
(this list is a bit bare https://help.libreoffice.org/7.6/en-US/text/sbasic/shared/keys.html?&DbPAR=BASIC&System=UNIX - and I think not complete as well, e.g. Ctrl+Shft+F8, but that's another topic)
Sounds useful. Other IDEs that I use offer similar features. +1 from me
