Can I? I know of course how to link to a thread, or any hyperlink for that matter. Is there a way of coding a link so that I can have the link drive straight to a given post?
This is what happens when we subscribe, but in looking at normal threads in my navigator bar, only the address of the overall thread ( or maybe thread + page # ) is shown. Can I link to a specific post?

Yes. The simplest way is to click the post number in the upper right corner of the post. A new window will open, containing just that post. You can then copy and paste the URL in the address bar. You can also simply right-click the post number and select the option to copy the link URL to the clipboard, which is even faster and easier.
As an example, my post above would be linked as:
http://boards.straightdope.com/sdmb/showpost.php?p=6570675&postcount=2
There’s also a way of linking directly to the post, but within the thread… Anyone know how to do that?
For that you need the post ID number:
http://boards.straightdope.com/sdmb/showthread.php?t=334510**#post6570629**
Note: this does not work for all browsers.
Test.
Doh.
Let’s just see if this worked… ( sticks tongue out of corner of mouth in facial gesture of complete concentration, etc. )
Oops. Hey that’s not what I meant but that’s a pretty nifty trick. Instead, I wanted to be able to …wait…what did Tell Me I’m Not Crazy do up there??
Hmmm.
So, where do I find the Post ID # ? The desire was to be able to link to a specific post line, a la what TMINC just did. I click on the post #, but that isolates just that one post.
What am I missing, and is it possible I’m missing it cause I am posting on a Macintosh?
I hovered over the number that you can click on, and checked the status bar at the bottom of my screen to see what the URL was. The post number is after the p= bit.
It’s lovely to come into a thread and all you have to do is say . . . thank you.

Another case of Dopers doing it for themselves.
An alternative method of showing the post in context is to use this vB code:
[****post=xxxxxx]post description[/post]
Another way to get the post number is to right-click on the “reply” or single post fields for the post and select “copy link location”, then paste it and edit it as needed.
Does it work? Huh? Huh?
Nope. It again posts as a single post, not at a specific location WITHIN a thread, so that someone can read the post but also the thread around it. Hmmmph.
What am I doing wrong . com. ?
I did right click on Reply this time, instead of the post # at upper right of post.
I don’t think there’s any way to do it in one step, Cartooniverse. You’ll need to get the anchor (the part after the #) manually. You can get the post number by looking at the p= part in the URL for the post in question, then make a link like this:
http://boards.straightdope.com/sdmb/showthread.php?p=6581960#post6581960
The p= part tells showthread.php to display the thread with post 6581960 in it, and the #post6581960 tells your browser to jump to that spot on the resulting page.

Actually, on preview, rowrrbazzle’s method works.
