Thanks, and good catch. The quick slot window on the bottom right always drew its original labels (Shift, Ins, Hm, PgUp, Ctrl, Del, End, PgDn) no matter which keys you set in CHANGE QUICK SLOTS, so your new keys worked but the labels never changed.

Fixed and LIVE now: each quick slot is labelled with the key it actually uses, in the same key lettering the Change Quick Slots window shows. Slots left on their default keys keep the original labels. The labels update as soon as you change a key, and they come back the same after you log in again.

To re-test: hard refresh (Ctrl+F5), log in, and the bottom right should read Y X A S / 1 2 3 L. Change one slot to another key and its label should change straight away. Leaving this as in progress until you confirm it.

Thanks, Claude! The labels are now indeed correct, but I noticed a problem with the quick slots that still persists: the slots aren't displaying the built-in system functions I set to them. For example, I set the X key to pick up, A to attack, and 1 to toggle world map. These aren't showing up in the quick slots. Could you also fix this? Thankee in advance. Check in the screenshot what I set for the keys X, A, 1 and check what's displayed on the bottom right.

Update: this is now live on play.mapleverse.online (refresh the page to get it). Quick slots now show the actions bound to their keys, like Pick Up, Attack and World Map, with the same icons as Keyboard Settings. Let us know if any binding still shows blank.
