[Need guidance for creating a macro to split screenshot into two images... left and right halves.]

Allow me to thank each or you for your much appreciated assistance and gracious replies, to what must have seemed to be a really dumb question. I'm so glad I found this site and hope that I can contribute along the way. Admittedly, I never expected for this forum to be so incredibly helpful (and even humbling).

Thank you one and all.

Honestly that is trivial to do and automate even further, without the need of Affinity at all, under MacOS! - To give you an idea, see the manpage for screencapture here (or perform "man screencapture" inside a MacOS terminal to show and read the man page there).

With "screencapture" you can automate the process without the need of cropping at all. So for example to take a screenshot of the whole screen/display you can perform:

• >   screencapture -T 2 ~/myscreen-full.png

  -T seconds  Take the picture after a delay of seconds, default=5
              Handy for arranging windows/menus before taking the screenshot.

Now suppose your monitor/display/screen has a resolution of let's say 1920 x 1200 pixels, screencapture also has an option to define the rectangular area to capture the  screen via the ( -R x,y,w,h   Capture a screen rectangle, top,left,width,height ) then. - So now in order to get a screenshot just of the left and right sides of our 1920 x 1200 pixel monitor we need just to perform ...

• >   screencapture -T 2 -R 0,0,960,1200  ~/myscreen_Lft.png
• >   screencapture -T 2 -R 960,0,1920,1200  ~/myscreen_Rgt.png

... which creates the two left & right halve screen captures of the monitor for us. You see no cropping needed at all!

The above shown screencapture commands can be automated, aka made more comfortable via Apple's/MacOS Automator and/or AppleScript. So you could for example start the process like an app with an associated icon from the desktop, show up an Ok panel first which when pressed performs the two screencapture call executions, or show up two textpanels for naming the captures then dynamically etc. etc.

Most interesting... thanks for the enlightenment! I automate the screenshot process with a "Keyboard Maestro" macro. One click and done. I had not, however, thought of restricting the screenshot to a definined area. Very slick. Old dog - new trick... I like it!

Thanks.

I assume the bolded left is a mistake and you meant the right half.....

Yes, it was... thank you. (Aging eyes and running one's hand through a table saw indeed increases the likelihood of typos and other such errors.

Most helpful... THANK YOU! I have downloaded all of Affinity's YouTube videos at 1080p! I had not, however, found these on Vimeo.

How in the heck do you tweak steps in a macro? (I can't even see the parameters of the steps.) 

How do you delete unused steps in finished macro?

Ho do you keep a macro loaded, so you don't need to recall it for every image?

Thank you... I'll give it a try.  I'll be surprised if Affinity Photo will do it faster than my current CS6 macros, but I hope you're right. The main advantage to CS6 right now is that I've used it for decades and don't even need to think about it when I create a macro. But once I get used to the major differences between the two platforms, I'm sure it will be easier!

Thank you for your reply and assistance. I'll let you know.

PS: Before even starting to edit the screenshots, I rename all of them incrementally... from "1.png" to ###.png. By adding the "_Lft" and "_Rgt", I simply open ALL of the cropped images at the same time, and they naturally sort in proper order. I could use anything else as well, but this is convenient and easy to distinguish. If I only use a part of the screenshot and do not split left/right, then I simply save them with the same name (but in another folder, nonetheless).

I purchased the entire Affinity suite when it was first released as a Beta. But I had been using Photoshop CS6 so long (and knew it so well) that I never made the effort to switch. Now that I'm on macOS Monterey, CS6 is no longer available. On PS, I used macros extensively and could create what I needed without even thinking about it. I'm confident that I will soon have the same comfort level with Affinity products. But this old dog needs some help in learning my new tricks!

My challenge at present is to take a full screenshot and turn it into two pages, one comprising the left half of the screen and the other comprising the left half of the screen. I'd do this for a number of similar screenshots and, when finished, I'd combined them into a PDF book. The process I used in PS was to crop the original to half the size (left side first), then save it with the same name, appending "_Lft" to the name. Then undo the crop and repeat for the right side, appending "_Rgt" to the name instead. Close the image  and continue to the next. I would either load all the screenshots at once and automate it to all, OR I would simply batch process through all full-size screenshots within a given folder.

For some reason, I'm having an issue getting my head around creating the process in Affinity Photo (age, most likely). Any assistance in regard to the best approach would be greatly appreciated.
