I'm not really sure how much time you will save, but you have ability to do what you asking for in all variables (F2), only problem is When you use Alt+F4 to close it, it never open again (its Bug) you need to restart the Project Maker. Anyway, its super fast, have a look

What would save us even more time, its ability to use more keyboard shortcuts, like closing all those popup - specially I hate when I need to comment on every action, its super annoying.
