Need a Simple Way to Handle Modifiers for Non-ASCII Keys

[Sleepy]

I find that the above action isn't working (yes, I do have "Press and Hold" selected.) Someone else reported that the action wasn't working here, four years ago:

Type a keystroke actions not working as expected

I’m trying to simulate a keypress (right arrow) with a command modifier using the Type a Keystroke and Type Modifier actions. I have a modifier action set to press and hold followed by type a right arrow keystroke action. I would expect this to put the marquee at the end of the current line in the currently active window. All it does, though, is shift the marquee one character to the right. I’m working around it by using an applescript action but this requires the code to have a couple of 1 sec…

And the response was to not use this action. Well that advice doesn't work for me, for reasons stated in my first post. So can someone confirm the above post that the "Type the Option Modifier (and Press and Hold until end of macro)" action doesn't work? Why was the user told not to use this method to press modifiers?

I found an AppleScript command that looks like this:

tell application "app-name" to key code 124 using option down

The problem is that the word "option" appears to be an AppleScript keyword, not a variable/string, so it doesn't give me any advantage over KM, which also requires hardcoded modifiers.
