LOL: Add more hotkeys to cast spells in Lands of Lore

[Michoko92]

Hi,

Thank you for making Lands of Lore playable with ScummVM, this is awesome. I'd have a request though, please: being able to cast spells with keyboard shortcuts would be incredibly useful, as the UI is quite clunky and requires super precise aiming with the mouse. Moreover for people with disability or using controllers like the Steam controller or Steam deck, it would be super handy to be able to map those shortcuts.

It is currently not possible to automate spellcasting with programs like AutoHotkey, because depending on the number of characters in your team, the portraits and UI are not always in the same screen space.

My suggestion:
Cast spells of character 1 with Shift+[1-4]
Cast spells of character 2 with Ctrl+[1-4]
Cast spells of character 3 with Alt+[1-4]

Thank you so much to anyone considering this addition, which would definitely be a game changer. Cheers!
