You can use screencapture
commandline utility. Create an Automator Service (takes no input) which will do a shell command and assign keyboard shortcut to it.
The shell script will look like this:
/usr/sbin/screencapture -R0,0,1000,400 /path/to/save/FileName$(date +"%m_%d_%Y_%H_%M_%S_%s").png
screencapture
has -R
modifier not listed in man
but it's listed in help as:
-R<x,y,w,h> capture screen rect
The values I used above captured this image which also shows how the rect coordinates worked.
Change x,y,w,h
values for those You need.
The date +"%m_%d_%Y_%H_%M_%S_%s"
adds a timestamp to the file name
You can actually use Screencapture to find the rect you want by using cmd +shift+4 which will give you some cross hairs with the numbers on for click drag release capture rect.
In Terminal.app typing: /usr/sbin/screencapture -h
will give you the help documentation
