I am making a macro where I need to check if clipboard has changed after I press cmd + c.
How can I do it?
I am thinking of something like this but not sure if that is the best way and I am still not sure how to reference variables. 
Is this a good way to do it?
Thank you for any help.
I used to use a similar method, until I discovered:
function:CLIPBOARDSEED [Keyboard Maestro Wiki]
I now think this is the best method to use.
I just posted an example macro showing how to use this:
To not forget the obvious: there is also a macro trigger for clipboard changes:
Good point, Tom. But that is NOT a choice you can use within a macro to determine if the user has made a selection before the COPY command.
Yes, Michael, thatβs clear. But from the OP itβs not entirely clear to me, wether the test has to be done within a macro, or if a standalone test serves as well βor better.
WTF? How am I just hearing about this? I've read lots of discussions on the subject of how to know when a COPY has finished, and I've never seen this mentioned.
So this appears to work:
Unbelievable.
And thanks, BTW. 
To paraphrase an old, sexist saying:
So many
women, er a, KM features, so little time till I check out.
Sorry ladies, no offense intended, but feel free to insult me. That was an expression from my much, much younger days, which no longer applies. 
Hi, @nikivi. You might find this thread helpful: Get Selected Text, Otherwise Clipboard
Not in an if statement. Do this instead:
but with this I can't do branching or I must be missing something
Hi, @nikivi. How about this?

wow that's perfect
thanks a lot 
Glad this helped. Bear in mind, that it's possible that you could get some false positives. For example, if you have a file selected in the Finder, then local_Text will be set to the filename. That could be considered a bug or feature; it depends on your requirements.
This is unnecessary in recent versions - Keyboard Maestroβs Copy action will wait for the clipboard seed to change itself.
@_jims shows how to use this to determine if the action succeeded in a timely manner.
It turns out that you don't need to use "CLIPBOARDSEED()" with a copy statement. If the "Copy" succeeds, then something was copied. If it fails, then nothing was copied.
