It requires the Virindi Bundle (specifically: Virindi Views, and Virindi Hotkey System) so if you want to try it, you will need those installed.
The features: Hotkeys for buttons 1234567890-= (if you use - and = for selecting things, you'll need to either change the hotkeys in VHS or change AC's hotkeys) along with Ctrl+1234567890-= and Shift-1234567890-= are all icons you can drag either items or spells into, right from your inventory or spellbook or spellbar. You cannot drag armor from the paperdoll onto icons, although you can drag armor from slots.
Using something will attempt to equip or unequip it. There is no current way to cast spells out of a wand at the moment.
Healing kits, lockpicks, food of all kinds, mana stones and arrows will all automatically replenish themselves from your inventory if more are available.
Alt-1234567890-= switches pages.
You'll want to hold down the ctrl button to show the expansion buttons.
Also there are hotkeys that correspond roughly to the spellbar (insert - move down a page, pageup - move up a page, page down - go right, delete - go left) along with new hotkeys (home - move up a row, end - move down a row) and the button to use an item is now SCROLL LOCK (Note: if you use Virindi Tank, this is also a VT hotkey).
