How to make a slotted hole

New user here, progressing slowly.
How do I make a slotted hole? It would look like two opposing half circles connected by two straight lines. Something like the attached which I found in an existing design. Grateful for any pointers.

Slot tool.
Yes, I know that slot tool. My question was how to actually make a slot on a sketch. Do I first have to draw a line or a point? Just clicking the slot tool and then trying to draw doesn't give me anything.

Yes, you first need a line. Then use the slot tool on the line -it uses the line as a centreline for the slot, with the radii centred on the endpoints of the line.
You can also select splines and arcs, not just a line.
Have you tried the learning center? This and many other sketching techniques are covered in sketch training for free.
Also if you hover the mouse over the tool selection you'll get a brief description. In this instance the description is "make a slot by selecting line, spline or arc". They can be used in combination as well.

Yes, I got that far. Drew a line on a sketch and put a slot around it. But I keep getting error messages like 'not fully defined' and the slot remains red in the list of items. I can extrude it 'through all' and it looks OK but the outline remains in blue and I can't get the dimensions/position to display.

Is the centerline selected for the slot completely constrained? See the difference between sketch 1 & 2 in this example. Sketch 2 shows as not fully constrained even though its the same. In sketch 1 the centerline is constrained.
If you are seeing red in the sketch feature list post a link to your document for a review since something else is wrong. Maybe something over defined?

Hmmm. I need to learn what 'constrained' means, and how to manipulate it.Thanks guys, I now have a direction!

Good learning resources here:

With help from my friend Cor van Doorn, I have it like I want. Had some error messages like 'not completely regenerated' and 'undefined' but now understood their origin and solved them. I also understand why all elements have to be constrained to something, that was a new concept I needed some time to grok. Onwards, always onwards!
