Hello! I'm new to alfred and I'm trying to create hotkeys to launch the apps that I'm frequently using. I know that it can be done using alfred's workflows, but I don't like my hotkeys to be global. Instead, I want the hotkey's scope to be limited to alfred. In quicksilver, I can do this by setting up a trigger, binding it to a hotkey, and limiting it's scope to only quicksilver. For example, I set opt-r to open chrome, but I actually have to press opt-space first to activate quicksilver and then opt-r to open chrome. This allows me to define hotkeys without worrying whether it would clobber another app's existing keybindings. Is it also possible in alfred?
