i am a new user,the first time i test why wrong?
^&{Space}::{LCtrl} & {LShift}
Error: Invalid hotkey
Re: Error: Invalid hotkey
Many reasons. First, for the hotkey definition, you don’t use braces around the key names, and if you want to use a modifier symbol, you don’t use &, which is for a custom combination of keys (and if you do use &, you would put spaces around it). So the hotkey for Ctrl+Space is ^Space::.
It is not clear what you want to happen when you press that hotkey. Do you just want to press and release the left Shift and left Ctrl keys? Or do you want them held down as long as you hold down the hotkey combination? Or something else?
