commit 325fd8feb1e6b78f189483feeb4fc937a5758479

    Added link operation to selection-mode.
    
    No unlink on [Undo] yet.
    I will keep the old link implementation for this cycle at least.
    It's necessary to improve link/unlink behavior for the next cycle,
    make it more robust. I'm thinking even at folks level.
