What would be the macro setup to open one or more selected files in a designated application? I thought it might be Move file action, but I'm not sure if that's it, or how to use it. Will it require an AppleScript? Thanks for your help.
Never mind, I figured it out. 
Hey Bakari,
That works well if you’re wanting to open files with a specific app.
If you want to open files with their default app then use the Finder instead of CS3 in Keyboard Maestro.
Here’s how to do both with AppleScript:
Default:
# Open Finder Selection with Default App for Each File.
tell application "Finder" to open (get selection as alias list)
App-Specific:
# Open Finder Selection with Specific App.
tell application "Finder"
set finderSelection to selection as alias list
end tell
if finderSelection ≠ {} then
tell application "TextEdit"
activate
open finderSelection
end tell
end if

Best Regards,
Chris
Awesome, thanks. Look forward to using this one.
Hi!
Which action is shown at the top ("Open in Photoshop")? I can't seem to find it. I just want to open a file highlighted in the finder in a specific application.
I tried this one, which says to option click on the file chooser icon in the action, but I think I'm doing something wrong or this is the wrong action?

Thanks!
It's actually the Open Finder Selection action. It changes its name in the KM editor when you specify a different application; here are a couple of examples:

Hey thank you!
All working now.
Thanks again!
