I then forked their repo and layered a lot more bindings on top, similar in a way to the Typist mod.
Mod features as described in my repo:
Selecting cards
Use [1] - [0] to select cards 1 through 10. To go above 10, use the +10 modifier [=]. For the playing cards hitting an already selected card removes selection; other card types can be only selected one at a time.
Selecting not-a-hand
In order to select Jokers, consumables (Specrtals / Tarots / Planets) and other slots, use modifiers that change your selection category:
[ J ] to select Jokers
[ C ] to select cards in a consumable area
[ V ] to select Vouchers in the shop
[ B ] to select Booster packs and their cards
For anything else (your playing hand and main shop slots) do not specify the category. As a shortcut, you can double the category key to select the first item in the category (for example, [ V ] + [ V ] to select the first Voucher)
Card actions
Once you've selected the card, you might consider doing something with it. Right now the following actions are supported:
[ W ] to buy the card from shop / redeem a Voucher / open a Booster pack
[ S ] to sell the card in your possession
[ U ] to use / buy and use consumable
[ , ] / [ . ] to move your card left/right in the hand order
[ H ] to display card information (usually available when you hover over it)
Other actions
[ Enter ] to play hand / exit shop / start a blind
[ Space ] to discard hand / skip a blind / skip a Booster pack
[ R ] to reroll the shop / the boss blind
[ A ] to open the Run Info window
[ D ] to open the Deck Info window
Hold [ Left Shift ] to peek at your deck information
[ Z ] / [ X ] to sort your hand by rank / suit
