    *List Printing:* If you paste a (Yet Another) Squad Builder, Fab's or
    xwing-builder.co.uk permalink into a channel I'm in (or direct
    message me one), I will print a summary of the list.\n
    *Card Lookup:* Say something to me (_<@r2-d7>: something_) and I will describe any upgrades,
    ships or pilots that match what you said.\n
    You can also lookup a card by enclosing its name in double square brackets. (Eg. Why not try
    [[Engine Upgrade]])\n
    If you only want cards in a particular slot or ship, begin your lookup with the emoji for
    that ship or slot. (eg. _<@r2-d7>: :crew: rey_)\n
    You can also search for cards by points value in a particular slot. Eg. _<@r2-d7> :crew: <=3_.
    =, <, >, <= and >= are supported.
