Help withAudacity to split track in two.

[Geek-9pm]

I forgot how to use Audacity.   
Here is where I am in the manual.
https://manual.audacityteam.org/man/audacity_tracks_and_clips.html
I have some voice tracks that I would like to split.
Example; A selection is almost 17 minutes long. I would like it to be about half size. I can find a place where it takes a pause and I can put a marker there. Now how can I simply break it into two?  Each half about  8 or 9 minuets.

Say the track was  named
News-Mar19.wav

I would like  it to  become
News-Mar19A.wav
News-Mar19B.wav

Is there some way to automate part of this? I could find the pause and put a mark there. The I would like to just hit a special key and it wold finish up the work.

Any ideas?

If you use Edit->Split, you can double click one or the other side of the split to select that section. You can then use File->Export Selection to save that section to a file. I don't know of a good way off-hand to automate the save/names after doing the split, though.
