How can i combine two functions into one, like macros or actions

I'm cropping around 500 document images. the images are not scanned correctly and has black borders around.

What i'm doing is i select the area want to crop and press ctrl-y to crop it then press ctrl-s to save. So what i want is to create a custom hotkey (lets say w) which will do both of this process for me at the same time. I think it will boost my productivity.

Instead of Ctrl+Y (Crop), use Ctrl+Shift+B (Save selection as)

Than it will open a dialog box for save as. In my method it just overwrites the original file. And I'm enabled some options in settings.

If your scans are properly aligned (vertical & horzontal) and the borders aren't too spotty, you could try auto crop in batch processing:

I am currently running 4.56 / 64 bit
Like the OP I have some 500 scans that need resizing. I am currently using Shift+V (-98px top and +6px alternatively left and right) Enter followed by Control+S, Enter and then the next file arrow but it is so SLOOOOOWWWW.
I see that one can use scripts but at 77 I am too old to learn how to write one.
I tried using the thumbnails bulk resize but there is no option to add/remove a specific number of pixels on a specific margin that I can see.
Has anybody got any hints to speed this?
Thanks
