(I've got to ask, because I can't believe no one else is thinking it)
I appreciate that when you post code you put it like this:
But if it is several k bytes in size, how is it done?
For me, I have to click the left most part of the line, drag select it all - which means moving the mouse right beyond the end of the line and ........ waiting. (and waiting and waiting)
Any slight movement up or down, you get the other stuff selected as well.
Not a bit deal as the thing is still scrolling to the right.
Then when at the end, you have to position the mouse at the end of the line (while holding the button down) then only select the code.
This is a new feature that got added in the most recent version of the forum software and I had been waiting for our forum to be upgraded to it. Your post reminded me to go check, and sure enough, the option was there.
And another... If you have two windows open - one with flow and one with the forum (or other source of code) - if you use the triple click - you can then just drag the code onto the flow editor desktop to import it.
