Move the cursor adjacent to the function name and press Ctrl-Shift-Space. A hint would pop-up.
Ctrl-Shift-Space didn't do anything when I tried it.
However, when I tried Ctrl-Space I ended up with a popup like this:
That's the sort of thing I'm looking for. However, it's kind of cumbersome because in order to get the information I have to perform three consecutive operations:
1. I have to click on the function.
2. I have to press Ctrl-Space to make the box appear.
3. I have to click off the box to get rid of it.
It would be far easier and more time-efficient for an information tooltip to appear when I mouse over the function, rather than having to go through all that hassle.
Does anyone know how to accomplish this? Thanks.
