Is there any way I can quickly cast a spell, or maybe even just recast the spell that I previously cast?
One difficulty I'm having in combat is that I'm kind of slow to click the runes for spellcasting, and I find that it slows down the overall attack speed of my party, since if I'm fiddling with the runes, I'm not swinging swords in the front ranks. First I have to right-click on the mage's empty hand to open the runes screen, then I have to click on the rune(s) I need for the spell, and then finally I have to click the button on the right to finally cast the spell. This is a lot of clicking.

Is there anything I can do to make casting or recasting of known spells more quick and automatic, or do I have to manually input the runes for the spell every single time I cast it? Are there any keyboard shortcuts?
