Currently in Logseq, you can copy the block ref while you are in a block without having text selected with meta-C.
I would like an additional option, where you could copy the selected text, place it in quotes, and append the blockref wrapped in an alias. (This can be incredibly useful, and was integrated into Roam42 with the command meta-j s)
Result: “selected text” *.
Ideally, this command could be added to the customizable library of keyboard shortcuts so users could assign their desired key binding.
