Option to use channeling skills as a toggle instead of holding down a button

The title says most of it. For me it hurts my hand to continually hold down a skill (mouse or keyboard). If there was a configurable option that let you use a channeling skill as a toggle i.e. by pressing the button once to make your character keep channeling until you tell them to do something that interrupts it, that would make these skills a lot more appealing to use.

Not only channeling, but any skill. Constant holding key is bad!

So need a special hotkey Use_Until_Interrupted. I want to press it once and see my char starts attacking until any other hotkey / mouse pressed (or just mouse).

Another hotkey is Move_Until_Interrupted. I want to press it once, and then char will follow the cursor until any other hotkey / mouse pressed.

Checkbox to make any other hotkey Interrupt / NotIterrupt two hotkeys above. So i can bind flasks and some instant spells to NotInterrupt hotkeys.

I can be banned for this, but i use ahk exactly for this two hotkeys, because otherwise i would break my hands and can't play at all.
