Is there any way to resize a selection to a specific pixel dimensions that I can type in?
I know I can right-click and do a transform with a mouse but that requires an extremely steady hand to get precise results.
See attached image: The selected region is 800x794 pixels. The whole canvas size is 1200 x 2907, as you can see at the bottom of the image. When I right-click on the selected region and select Transform, the tool settings at the top shows 600 x 1426 -- what do these numbers mean?! If I want to resize the selected region to, say, 400x397 what's the most efficient way to do this?
I know I can copy the selection into a new file and image-size that and then paste the result back into my layer but I have a bunch of these to do so I'd like to resize it in-situ if there's a way to do it.
Thanks in advance.

If it's selected, then you can enter the value you want to change its dimensions in the Transform section of the Properties panel (Window > Properties).

@peternelson when transforming a selection the 600 x x 1426 y are the coordinates for your current selection size. If you look a little more to the left you will see the matrix showing what point of origin the value is coming from. Be default its the center of the selection:
To the right of that is the w & h values that you can enter to resize your image. It will show % but you can enter px values:
Here is how I would do this. Start with the selection tool active and no selection.
In the options bar, you can change the Style to "Fixed Size" and then enter your values.
Now when you use the tool it will auto select a size of your choosing.

The numbers mean what they say, and although that sounds like a bad answer, the point is to look more closely at what it says:
You said it shows 600 x 1426, but that's not all it shows. What it actually shows, if you look closer, is:
X: 600 Y: 1426
So, those are X and Y position coordinates.
X = horizontal position
Y = vertical position
If you change those numbers, you’ll reposition the selected pixels.
You want to resize. That is the next set of numbers, which in your screen shot show:
W: 100%
H: 100%
W = width
H = height
Of course, you don’t want percent, you want pixels. So follow the advice in Kevin’s reply, and type the number followed by “px” to tell Photoshop you want to set the size in pixels. If you want a field’s value to be in pixels all the time, right-click the W or H value and choose Pixels, or to set the unit of measure for almost all fields at once, right-click the ruler and choose Pixels.
If you put together the advice in all of the replies so far, these are some general tips you can take away:

If the object/selection is on it's own layer, make it a Smart Object
